A mouse sperm of genotype a B C D E fertilizes an egg of genotype a b c D e. What are all the possibilities for the genotypes of (a) the zygote and (b) a sperm or egg of the baby mouse that develops from this fertilization?

Respuesta :

To know the possible number of genetical difference eggs you can have, you need to do

2^number of heterozygotes

If you have a B C D E x a b c D e = aa Bb Cc DD Ee

You have three heterozygotes. You have 2^3=8 possibilities.

The probability of producing a child that will phenotypically resemble either one of the two parents is the possibility of having each gene.

1/2 of B and 1/2 of b

1/2 of C and 1/2 of c

1/2 of E and 1/2 of e

1/1 a

1/1 D
