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?

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.

it is due to the halo effect as the impression of the boy created earlier.on the mind of the principle affected his decision
