does the chromosome from the female or male determine if the child is male or female and why?

The last two chromosomes decide sex.  Chromosomes carry DNA and decide in essense who we are when we start out life.  the lst chromosomes are special, they decide gender.  The egg will always carry an X.  The sperm can carry an X or a Y.  When it is XY then the baby will be male, XX is a female.  \n\nBut gender is not decided by the chromosomes in the same way that we do not simply see with our eyes.  Many sections of the brain are devoted to seeing, some people can see and now know what they see, some lack emotion responses to vision, and the like.  We are beginning to understand that what the chromosomes say do not totally influence gender.  Part of the mind decides what gender we feel, and despite what some feminists say about equality there are differences in the brains of males and females.  Horomones can have an affect on the developement in the womb as well.\n\nAnd yes it is true.  We are all females by default.  Since animals start off this way, I do wonder about Hyenas.  Er... yeah, if you know about the species than that weird comment makes sense...

Not that I'm aware of. This genetic condition involves the X and Y chromosomes, and not anything else.

It's because the Y chromosome isn't added until after the nipples are formed on a baby in the mother's womb. So, I guess technically, we're all females at some point in our existence.

Hermaphrodite is the correct name...This person is both male and female...it depends which sex/genda is more domineering as to what stands out.\n\nFor example:  A person looks female, but has a penis, but also has a uterus and ovaries for baby production.\nOr u can have a person that looks male but has a vagina.\n\nTo correct it depends on what the person wants there sex to be.  If they look female and want to be male they can have a hysterectomy where they remove all the uterus and leave them with a penis if they have them.\n\nIf it looks male then they do the opposite and can do the same surgery as above and make them female.

'Male and female human embryos are identical in the early stages of their development. If the fetus receives a Y chromosome from its father, a hormonal signal is produced: the labia fuse to form a scrotum, the gonads develop as testicles and a male results. Otherwise the "default" female remains.  Various structures in the adult reflect the symmetry of male and female and their common embryonic source. Men have nipples because they have already begun to develop when the "switch to male" signal is received. The development of breasts is halted in most--but not all--cases but the nipples are not reabsorbed.'

No. B'coz if a perosn is heterozygous for a trait, the person will express the dominant trait. And, so will a person homozygous (dominant allele) for that trait. Therefore, it's not possible to differentiate between the two unless one obtains their karyotype chart.

There's a lot of debate over how one can conceive a specific gender.  Some experts say it depends where you are in your fertile cycle; you're more likely to have a boy the more fertile you are.  I've also heard that if the woman has an orgasm during sex then the acidity levels in her cervix will kill off sperm with the female chromosome.\n\nThere's no easy way to be sure which sex your baby will be.  Just count yourself lucky to be able to get pregnant at all.  I've been trying for ages now!!

no actually she doesnt.\nbut i am quite sure she has XY chromosomes.  i seem to remember in genetics class talking about her as an example of a rare case in which a person has XY chromosome (male) but doesnt have the receptors to actually activate the chromosomes.  hence the fetus continues to develop as a female, which all fetuses begin as, sorta.  that is the internal sex parts are caused to drop down and become testicles by the Y chromosome. if they dont, you develop as a female.... make sense?  look it up... if you dont believe me..\ndq

The previous answer is incorrect.  It will produce a male offspring if it fertilizes an egg.  Males have a Y chromosone, females have x chromosones.

Flower\nIf both sexes are in the same flower (and plant) then it is a HERMAPHRODITE\nIf not, then they will be female and male plants (of the same species)

the presence (or absence) of a "y" sex chromosome.  If the "y" chromosome is present, male genetals develop.  Otherwise (two "x" chromosomes), the genetals will develop as female.  The sperm (male sex cell) has the "x" and the "y" possibilities.  (each only gets one).  The female sex cell (egg) only has the possibility of an "x" chromosome for the sex.  There is a possibility that an egg can form incorrectly and have two "x" chromosomes.  If the sperm for this type of egg is a "y" sperm, it will still develop as male.

Hmmmm, I read about that, trying to remember right.  When conception first takes place, the gender is not yet set.  Every baby intially can be male or female, the stem cells then become arms, heart, eyes, everything, including male genitals and prostate OR female genitals, womb and ovaries, and including the ability to grow breasts if the baby becomes a female.  Can't remember when it is that the gender becomes effective, but it's early on.

No. Don't confuse the common phrase that "we all start as female" with the individual set of chromosomes. XY embryos are male; the "activation", so to speak, of the factors that will lead that individual to have male characteristics (gonads, genitalia and secondary sexual characters) occurs some time after the start of embryonic development. Thus if one examines an earlier embryo, males are indistinguishable from females.\nBut they each have their XX (females) or XY (males) sexual chromosome pair, and the proteins coded in their genome will lead to normal development of either sex.

In females one of them is called a 'Barr body'\nBarr is name of a scientist\nIt is also one of the sex chromosomes

No. remember the sex depends on the sperm so that means that if a sperm carring the girl coding fertilizes the egg then it will be a girl but if one carring the boy coding fertilizes the egg then it will be a boy. \n\nAdded to this is that each sperm carries different coding so besides there being male and female sperm there are differences among them all.

having xxx sex chromosome.or a female with turner syndrome

In Turner syndrome, the girl does not have the usual pair of two complete X chromosomes. The most common scenario is that the girl has only one X chromosome in her cells. Some girls with Turner syndrome do have two X chromosomes, but one of the X chromosomes is incomplete. In another scenario, the girl has some cells in her body with two X chromosomes, but other cells have only one.
