(a)

Summary Introduction

To draw: A graph depicting the phenomenon of no selection with a range of phenotype (e.g. height) on the x-axis and number of the individual on the y-axis.

Introduction: The phenomenon of natural selection is based on the evolutionary changes that occur within the population.

(b)

Summary Introduction

To draw: A graph depicting the phenomenon of “stabilizing selection” with a range of phenotype (e.g. height) on the x-axis and number of the individual on the y-axis.

Introduction: The phenomenon of natural selection is based on the evolutionary changes that occur within the population. The mechanism of natural selection can be classified into three kinds: stabilizing selection, directional selection, and disruptive selection.

(c)

The MN blood group is of interest to population geneticists because (a) people with genotype MN cannot receive blood transfusions from either MM or NN people (b) the MM, MN, and NN genotype frequencies can be observed directly and compared with calculated expected frequencies (c) the M allele is dominant to the N allele (d) people with the MN genotype exhibit frequency-dependent selection (e) people with the MN genotype exhibit heterozygote advantage
1a) Define the term linkage disequilibrium. (b) Explain why it makes sense that natural selection can maintain linkage disequilibrium between two loci that are not physically linked when there is epistasis for fitness. (c) Explain the role of linkage disequilibrium in employing QTL mapping as a way to investigate the genetic architecture of adaptive traits.
