Summary Introduction

Introduction: Alleles are the alternative forms of a gene. Most of the genes consist of two alleles— recessive and dominant alleles. The dominant trait gets expressed only when the organism is heterozygous for that particular trait.

Why do recessive lethals persist in a population? Provide an example of a recessive lethal allele.
Your parents are studying the evolution of the pumpkin size to make the best patch in your city. After doing some crosses and genotyping some individuals, you determined that the number of individuals homozygous dominant for the largest pumpkin allele is 98, 80 are heterozygous for medium size, and 20 are homozygous recessive for small size. What is the allele frequency for the homozygous dominant allele? Please round up and your final answer should have four decimal points.
(a) Assuming that Migaloo’s albinism is caused by a rare recessive gene, what would be the likelihood of the establishment of a natural robust subpopulation of albino white humpback whales in this population? (b) Assuming that Migaloo’s albinism is caused by a rare dominant gene, what would be the likelihood of the establishment of a natural robust subpopulation of albino white humpback whales in this population?
