Chapter 15, Problem 1FIB
Summary Introduction

Introduction:

The Hardy-Weinberg principle states that “allele and genotype frequencies” are remaining constant in a population, from one generation to the next. In a given population, if the gametes donated randomly to the next generation, would lead to unchanged allele frequencies.

Answer to Problem 1FIB

Correct answer:

The Hardy-Weinberg principle provides a simple mathematical model for a non- evolving population, also called an equilibrium population, in which allele frequencies do not change over time. No such populations are not likely to be found in nature.

Explanation of Solution

The Hardy-Weinberg principle defines populations which are no longer evolving, and known as “equilibrium populations”. This type of populations does not consider changes in “allele distribution” from one generation to the next generation. This principle applies only when evolution does not occur in a population.

According to this law, “allele and genotype frequencies” in a population remain constant from “generation to generation”. In a given population where gametes contribute to the next generation randomly, allele frequencies will not change. This law is “not” applicable on “real population”.

Conclusion

The Hardy-Weinberg principle defines about “genotype and allele frequencies” that remained constant from one generation to the next.

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…
