In a certain breed of cat, short hair is a dominant trait over long hair. If a heterozygous female cat is crossed with a long-haired male cat,what percent of the offspring would have the same phenotype as the father? (SC.7.16.2) 0% 25% 50% 75%

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