To solve this problem, we need to understand the inheritance pattern of the hair length trait in cats.Given information:- Short hair is a dominant trait over long hair.- The female cat is heterozygous, meaning she has one dominant allele (S) for short hair and one recessive allele (s) for long hair.- The male cat has long hair, which is a recessive trait.Let's represent the alleles as follows:- S: Dominant allele for short hair- s: Recessive allele for long hairThe female cat's genotype is Ss (heterozygous), and the male cat's genotype is ss (homozygous recessive).When the female cat (Ss) is crossed with the male cat (ss), the possible genotypes of the offspring are:- Ss (short hair)- ss (long hair)The probability of each genotype is 50%, as the female cat can pass on either the S or s allele with equal probability.Therefore, the percentage of offspring that would have the same phenotype as the father (long hair) is 50%.The correct answer is .
