Hardy-Weinberg equilibrium states that in a population genotype and allele frequencies do not change even after several generations in absence of some evolutionary factor like mutation or migration. According to it, p + q = 1 and p 2 + 2pq + q 2 = 1 where, p = frequency of dominant allele q= frequency of recessive allele p 2 = frequency of homozygous dominant genotype 2pq = frequency of heterozygous genotype q 2 = frequency of recessive genotype

Summary Introduction

Introduction:

Hardy-Weinberg equilibrium states that in a population genotype and allele frequencies do not change even after several generations in absence of some evolutionary factor like mutation or migration. According to it, p + q = 1 and p²+ 2pq + q² = 1 where,

p = frequency of dominant allele

q= frequency of recessive allele

p²= frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q²= frequency of recessive genotype

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…
