Question

In cats, the allele for long hair is recessive to the allele for short hair (so short hair is dominant). if two cats that are heterozygous for hair length (aa x aa) have offspring, what percentage of the offspring will have long hair.

Answer 1

25%,1:3 This is due to the heterozygous condition to produce on homozygous long and one homozygous short then two heterozygous short.ie 1:2:1,but short is dominant and heterozygous short ate taken to be short ,thus modifying the ratio to 1:3,1:3 is 25%:75%.therefore homozygous long is 25%.
