Question

In a population of 1500 individuals, researchers observed a Y-linked condition in 5 men. What is the frequency of the allele underlying the condition in this population? Select one: 0.997 0.057 0.943 We do not have enough information to determine this allele frequency 0.0033

Answer 1

The population size is 1500. Of these individuals, 5 men are having a Y-linked condition. Since, the condition is Y-linked, the allele encoding for the condition is present only on the Y-chromosome.

Now, the Y-chromosome is present only in the males and not in the females. Thus, the total number of Y-chromosomes and hence the total number of the alleles present at this locus in the population is the same as the total number of males in the population.

However, no information about the number of males or females is provided here.

Thus, we do not have sufficient information being provided here to determine the allele frequency.
