Question

In cats, the allele for short hair (H) is dominant to the allele for long hair (h). A heterozygous short-hair cat is crossed with a long-hair cat. What percentage of the offspring is expected to be heterozygous for hair length?

Answer 1

Answer:

50% of the offspring is expected to be heterozygous for hair length.

Explanation:

50% of the offspring is expected to be heterozygous for hair length.

Heterozygous short hair (Hh)

Long hair cat (hh)

When both of them are crossed they produces offspring with genes:

Hh, Hh, hh,  and hh

Hh - Heterozygous short hair

hh- dominant long hair.

So we can infer that 50% of the offspring (2 out of 4) is expected to be heterozygous for hair length, which is heterozygous short hair.

Answer 2

An allele is defined as the variant form of the gene, which is present on the same locus of the chromosome as a gene. The allele codes for the different traits of organisms.

The percentage of the offspring having heterozygous genotype for hair length is 50%.

The genotype of the short hairs is dominant over the long hairs. Short hairs in the heterozygous condition are represented by Hh and long hair has genotype hh.

The cross between heterozygous short hair and purebred recessive is given in the attachment below.

Therefore, 50% of the offspring will have short hair with the genotype Hh.
