Can a female with an 'XXY' chromosome still give birth to a normal offspring??

XXY is called Klinefelter's Syndrome. Individuals with Klinefelter's are male instead of female, and they are almost always sterile.

B is the correct answer.  Females have 2 X chromosomes so they cannot contribute a Y chromosome to a zygote.  Also to be male a Y chromosome must be present (and posess the SRY gene).

To answer your question....yes.  The egg cells of the female all carry X chromosomes.  The sperm cells can carry either X or Y.  So basically, the sex of a mammal depends on the male, and which particular sperm fertilizes the egg (X).  If an X sperm fertilizes the egg, you have XX, which is a female, and if a Y sperm fertilizes it, you have XY, which is male.  This is why some sex-linked traits are more visible in males, such as color blindness, but that's a whole different post.

Hermaphrodites can if they have all of the normal female innards and ovulate, transexuals cannot because they do not have a uterus. Think about the umbilical cord... if their body can make one for the baby than the baby will survive.

Turner syndrome encompasses several chromosomal abnormalities, of which monosomy X, is the most common. It occurs in 1 out of every 2,500 female births. Instead of the normal XX sex chromosomes for a female, only one X chromosome is present and fully functional. This is called 45,X or 45,X0, although other genetic variants occur. In Turner syndrome, female sexual characteristics are present but underdeveloped.\nclick here:http://en.wikipedia.org/wiki/Turner_syndrome#Symptoms

Yes, but there is an increased risk of their child also having Down Syndrome. Sometimes very mentally retarded people are sterile though, so if this is a question pertaining to a certian someone you know, they'd need to get a check up to find out for SURE.

Sept. 27, 2005 --  A baby born outside of her mother's uterus is raising questions about whether or not men can conceive.\n\nToday Emylea Tharby is a healthy 4-month-old, but there is only a one in 10 million chance that she is even alive. \n\n"When we did the MRI, we put two and two together," said Dr. Renato Natale. "We couldn't see a uterus around the baby."\n\nEmylea developed outside of the womb when a fertilized egg fell into her mother's abdominal cavity. The placenta that feeds the baby was planted outside of the uterus. \n\nThe baby was delivered during emergency surgery with minor disabilities.\n\n"She's the most beautiful child I could ever dream of having," said Emylea's mother, Lia Tharby. \n\nThe successful pregnancy without a womb raises questions as to whether a man could one day become pregnant.\n\n"Good Morning America" medical contributor, Dr. David Katz, weighed in on the debate. He said men would need the female hormones necessary to sustain a pregnancy.\n\n"Could it be done? Yes," Katz said. "But there would be unpleasant side effects for a guy. I wouldn't rush off to try that."

the female has 2 X chromasomes;\nthe male has 1 X and 1 Y chromasome; interestingly enough, it's the male who decides what gender a baby is going to be because either one X chromasome from the mother  joins with his one Y chromasome or his one X chromasome. It's kinda cool. ; )

Yup. A full blown hermaphrodite is someone born with 2 sets of genitalia. They're usually outwardly female in appearance. (there's some features on ladies that're hard to hide) There's also other genetic disorders that result in various other,....degrees  I guess is the best way to put it of dual-genderism.  Sometimes  people are born completely female but with vestigal testes which are contained internally.

It is slightly more complicated. Prenatally a baby has what are called ovatesties. These will either become ovaries or testicles. On the Y chromosome is a gene (SRY) sex determining region of Y chromosome. It can get put on an X if a mutation occurs. Anyway sometime during development the SRY gene get turned on. This produces testosterone will cause the rest of he sexual organs to develop. \nThe X chromosome contains many genes that can produce different affect in different cells. Only one is need (the other is a Barr body) and the other has many functions in the cell. If you look at a calico cat for instance this will show you the best example. A calico being female has too X chromosomes. In some cells the maternal X is active and in others the paternal X. This shows up in the coat pattern.

The mother and child will have *nearly* identical DNA.  There will be a few mutations because mutations are ubiquitous, but 99.99+% of their DNA will be the same.

that's really rare but it has happened before.  It has to do with the chromosomes and how they are activated and crossed over and everything...it's complicated.

As a species, no. A sexually reproducing species has to have an EVEN number of chromosomes.\n\nAs indivdiuals, sure. There are thousands of individuals walking around today who have 47 chromosomes.

YES, as I was surprised to learn, the person is called a "chimera"...it's a REAL medical condition!\n\nshort, but informative article:\nhttp://www.thetech.org/genetics/ask.php?id=23

x x -> color-blind female\nX Y -> normal male\n----\nx Y ; x X -> offsprings\n\ngiven the conditions, the chances are:\n0%  to have a color-blind daughter\n\n50% to have normal but carrier children\n50% to have color-blind children\n\n0% normal sons\n100% color-blind sons\n0% color-blind daughters\n100% normal but carrier daughters\n\nsince red-green color-blindness is a recessive trait, the mother would have the trait in both her x chromosomes. the father had normal vision so he would have the normal gene which is dominant for the trait. \n\nsince males get their x chromosome from their mother and the y chromosomes from their father, all sons borne would be color-blind because whatever the x chromosome they receive from their mother would have the gene for color-blindness. though the trait is recessive, this one gene would be enough to manifest itself because males only have one x chromosome. \n\nsince females get an x chromosome from each parent, all daughters would get a normal x chromosome from their father and an affected x chromosome from their mother. and because females have two x chromosomes and color-blindness is recessive, they would need to have two affected genes for the trait to be manifested thus all daughters borne would have normal vision. the dominant gene they received from their father would mask or overpower the affected gene they inherited from their mother. however, these daughters are also called carriers because the affected x chromosome they received from their mother can be passed on to their own sons wherein the color-blindness trait can then be manifested.

Scientists have reported that they've found an "extremely unusual" trait in the cells of some mothers with two or more gay sons, providing more evidence to suggest that homosexuality might be inherited.\n\n\nMothers of multiple gay sons were about six times more likely than other women to process their X chromosomes in a certain way, researchers discovered.\n\n\nResearchers aren't entirely sure what the findings mean, said study co-author Sven Bocklandt, a postdoctoral researcher at UCLA. Making things more complicated, about 75 percent of mothers of multiple gay sons don't have the trait.\n\n\nStill, the study, released Tuesday in the journal Human Genetics, raises plenty of questions, Bocklandt said, especially as researchers try to figure out whether homosexuality has genetic roots and if there truly is a "gay gene" -- or genes.\n\n\n"What everybody wants is the gene, and we don’t have it yet," Bocklandt said. "But this is an independent confirmation that the X chromosome is involved."\n\n\nBocklandt and colleagues looked at a phenomenon known as X-chromosome inactivation, in which cells inside the bodies of females automatically turn off -- or inactivate -- one of their two X chromosomes. That leaves them with one working X chromosome -- just like males, who have a single X and a single Y chromosome.\n\n\nNormally, each cell in a female's body randomly turns off one or the other X chromosome. In some cases, such as when families share a genetic disease, there is "extreme skewing" -- one X chromosome is more likely to be turned off than the other, Bocklandt said.\n\n\nIn the new study, the researchers looked at 97 mothers of one or more gay sons and 103 women with no gay sons to see what their blood cells did with their X chromosomes. The researchers recruited many of the women with the help of PFLAG.\n\n\nThey found that nearly a quarter of the mothers of multiple gay sons inactivated the same X chromosome -- in other words, nonrandomly -- compared to just 4 percent of the women without gay sons. Of those with one gay son, 13 percent inactivated the same X chromosome.\n\n\nDr. Ionel Sandovici, a genetics researcher at the Babraham Institute in Cambridge, England, who is familiar with the research findings, cautioned that the study is small, with just 44 mothers of multiple gay sons being examined. More research in larger groups must be done to confirm the results, Sandovici said.\n\n\nThe research does provide "circumstantial evidence" that the X chromosome contributes to the development of male sexuality, Sandovici said. But "we still understand very little about molecular mechanisms of sexual orientation, and this seems to be rather a complicated biological puzzle."\n\nBut of course its Nature vs. Nurture and its possible that the person could just become gay because of his environment/experiences or just be born that way.
