Genetic drift refers to the change in the relative frequency of distinct genotypes in a small population, owing to the chance vanishing of specific genes as individuals do not reproduce or die. In the given case A, the population included 500 individuals of females and males in which the males compete heavily with the females for harems. In the given situation, the females give birth to one offspring in each season. In the case of B, the population includes just 250 individuals, and in this, the mating bond between the females and males goes through the mating season. In the given case, the females on an average give rise to 3 to 4 offsprings in a season.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
