In some cats the gene for tail length shows incomplete dominance. Cats with long tails have the genotype “LL”. Cats with short tails are “LS”, while cats with no tails at all are “SS”. For each of the following construct a Punnett square and give the genotypic and phenotypic ratios of the offspring.

a) A long tail cat (LL) and a short tail cat (LS)
Genotypic Ratio:

Phenotypic Ratio:

b) A long tail cat and a cat with no tail

c) A short tail cat and a cat with no tail

Phenotypic Ratio:

d) Two short tail cats
