NEET BIOLOGY

Detailed explanation-1: -Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.

Detailed explanation-2: -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-3: -The dominant allele is always the most common allele in the gene pool.

Detailed explanation-4: -The frequency of the “a” allele. Answer: The frequency of aa is 36%, which means that q2 = 0.36, by definition. If q2 = 0.36, then q = 0.6, again by definition. Since q equals the frequency of the a allele, then the frequency is 60%.

Detailed explanation-5: -Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time.
