In a population of 100 cats, 36 were white and 64 were black. If the black allele is dominant over white allele, what is the frequency of black allele in this population of cats?

Question

In a population of 100 cats, 36 were white and 64 were black. If the black allele is dominant over white allele, what is the frequency of black allele in this population of cats?, 0.64, 0.4, 0.6, 0.48

MARKS App · Accepted Answer

According to Hardy Weinberg's equation, p + q = 1 , where p is the frequency of the dominant allele and q is the frequency of recessive allele in the population. In the given data, 36 cats are white. They have to be pure homozygous individuals have recessive alleles. Thus q 2 = 36 / 100 and q = 0.6 . Thus p = 1 – 0.6 = 0.4
