The offspring from a cross between a red snapdragon and a white snapdragon are pink. How is this possible?

I'm not totally sure on this, just guessing what my mum has told me, and seeing how she gardens a lot, I'll assume it's true: The red and white seeds can grow together, to form a hybrid, adding a percentage of both colors to form pink. Hope it helps!

Well according to the internet it is pink, though I find it odd I can only find that information on trivia sites and not on sites about hippos.  I'll do some more research and let you know.

yes, its called a true hermaphradite, and it is due to a hormonal problem during development of the fetus.  rare.

Everything about a life form is decided by DNA from the colour of it's fur or skin to it's size. This is what our parents pass on to us. However, if this is not copied properly when it is passed on to an egg or sperm cell, which becomes a baby, then the baby may have a different characteristic from the rest of its species. This is called a mutation. If this mutation gives the animal an advantage over other animals in it's species- for example if it makes a moth brown instead of white so it can blend in on trees more, and is less likely to be eaten by predators, then that animal is more likely to survive. If it then mates and passes on it's mutated DNA to more offspring then they are more likely to survive so slowly the white moths would be eaten where the brown would not, and the species has 'evolved' to be brown. Every animal you can think of has been formed by tiny mutations over millions of years. We owe evolution quite a lot!

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.

i dont know, social trends are just weird like that.  its a good question.  i personally think its weird that pink has a unigue name.  isnt it just light red? light green and light blue dont have totally different names.  that makes it sound more masculine, too.  "light red"  :)

identical come from one egg that split when fertilized and fraternal come from 2 separate eggs. Identical are together in one 1 sack and share a placenta fraternal are in separate and each have a placenta-same with triplets and quints.\nThat's why identical triplet and Quints are SO rare.

If this were possible which it is not then what you would have is spontaneous cloning.  The offspring would not only be female it would be an exact duplicate of the mother.  There is no genetic material available in human females to reproduce anything other than a clone without fertilization.

Cross Fertilization refers to the crossing of species... for example, if you take "male" gametes from a green pea plant and mix them with "female" gametes of a yellow pea plant, you will find the progeny is a mixture of both species... you get green and yellow peas.

No:\nThey too distantly related.\nAlso their chromosome number and chromosome and shapes and gene layout, and individual genes are vastly different, so they cannot pair up in the fusion that is part of of the fertilisation reaction.

Yes, it is very possible.  O negative means that the child has 2 recessive alleles (genes) for type and 2 recessive alleles for Rh factor.   Therefore, his genes would be oo --.\n\nThis is possible if both parents are heterozygous (have both a dominant and recessive form) for both traits.  That would mean Ao +-.  The A overrides the o and so does the + vs. -.  They show A+ then.  They both give the child the o and - ===> oo --, or O-. \n\nStatistically, 1/4 of their children can be O type, while the other 3/4 appear as A.  Same with + vs -.  One fourth would be negative while the other three fourths would be positive.

Scientificly it's heredity and changes from their parent but generally God created them that way and he can put whatever color he wants on a butterfly

all normal males are XY.  all normal females are XX.  the female always donates 1 X chromosome to the offspring.  the male donates either an X or a Y to the offspring (50% chance of each event).  If the male donates an X, the offspring will be XX and female.  if the male donates a Y, the offspring will be XY and male.

Its called a "Chimera"\n\nIn response to the response below about tetraploidy.  Tetraploidy is highly lethal.  The person asking the question is referring to a tv show where there are people who have "two sets of chromosomes."  Not two identical sets in the same cell that didn't undergo mitosis correctly (and maybe meiosis).  The question is asking about people who have their "twin inside of them."  A condition where a fraternal twin egg is ingulfed by the other egg resulting in a chimera.  Check the references:

Assuming Black is dominant (B) and Albino is recessive (b)\n\nThe first cross produced all black\nbb x BB\n---B-----B\nb Bb----Bb\nb Bb----Bb\nFrom here, you can see that all the offsprint have one dominant Black gene, so they will all be black.\n\n\nThe second cross had about half albino\nbb x Bb\n---B-------b\nb  Bb-----bb\nb  Bb-----bb\nFrom this one, you can see that half of the offspring are homozygous recessive bb, and are albino.\n\n(Ignore the ---- in hte cross, they don't mean anything, they are just for spacing because yahoo deletes multiple spaces)

The closest answer is D\n\nI suggest you to give it a try yourself first.\n\nFirst try to visualize how many different types of gamates will be there. You will see two types A and a\n\nNow, draw a punnet square & cross them. You will get only one possible offspring i.e. Aa in the first filial generation.(F1 generation)\n\nNow, on performing self cross on two Aa individuals in the similar fashion, you will get a 3:1 phenotypic ratio and a 1:2:1 genotypic ratio in the F2 generation.

There is no crossing over during prophase 2! It's a fact. That answers your question pretty nicely.
