Question

In a genetic cross between aabbccddee and aabbccddee what fraction of the offspring will be homozygous dominant for all five genetic loci?

Answer 1

Answer:

None

Explanation:

The desired homozygous dominant genotype is AABBCCDDEE. To have an offspring with genotype "AABBCCDDEE", at least one copy of the dominant alleles for the genetic loci should be present in either of the parent. However, both the parents are homozygous recessive for all the five mentioned genetic loci and therefore, cannot have a progeny with homozygous dominant genotype "AABBCCDDEE". All the progeny of a cross between the two parents each with genotype "aabbccddee" would have homozygous recessive for all the give loci.

aabbccddee x  aabbccddee =  All aabbccddee
