Question

N cats, having a short tail is recessive to having a long tail. If a mother cat is heterozygous for this trait and a father cat is homozygous dominant for having a long tail, what will most likely be true about their offspring?

All will have long tails.
All will have short tails.
About 3/4 will have short tails.
About 1/2 will have long tails.

Answer 1

Answer:All will have long tails.

Step-by-step explanation:

Answer 2

The correct answer would be "All will have long tails".

Let us assume T and t as the alleles of the gene responsible for the length of the tail.

T is a dominant allele which codes for the long tail whereas t is the recessive allele which codes for the short tail.

The genotype of the mother cat is heterozygous dominant, that is, Tt.

The genotype of the father cat is homozygous dominant, that is, TT.

The cross would result in the production of the offspring with two possible types of genotypes TT and Tt.

Thus, all the offspring would have long tails.
