What will be the result in F2 generation when a
homozygous white male rabbit is crossed with a
homozygous black female rabbit if all the
progeny obtained in F1 are black?

Answer 1

Answer:

3 black rabbits and 1 white rabbit

Explanation:

Since in F1 generation ,only black rabbits were produced,it shows that black colour is a dominant character and therefore require only one copy to exhibit the character. So,in F2 generation the rabbits having genes BB,Bb,Bb,bb will be produced.Therefore the genotype ratio is 1:2:1 & phenotype ratio is 3:1 .
