NEET BIOLOGY

Detailed explanation-1: -An allele frequency is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population. Allele frequencies can be represented as a decimal, a percentage, or a fraction.

Detailed explanation-2: -How many different fur color alleles are in this rabbit population? How many different genotypes are in this rabbit population? There are two alleles for fur color–F and f. The FF and Ff genotypes give rise to the completely brown fur phenotype.

Detailed explanation-3: -Calculate the Relative Fitness (w) of each genotype by dividing each genotype’s survival and/or reproductive rate by the highest survival and/or reproductive rate among the 3 genotypes.

Detailed explanation-4: -To determine q, which is the frequency of the recessive allele in the population, simply take the square root of q2 which works out to be 0.632 (i.e. 0.632 x 0.632 = 0.4). So, q = 0.63. Since p + q = 1, then p must be 1-0.63 = 0.37.
