Amouse 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?

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

i think the answer is c hope this

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
