Chapter 3, Problem 52P

a.

Summary Introduction

To determine: The implication of the results regarding the location of the stopper mutation in the genome.

Introduction. The different forms of an allele in two organisms of the species can result in changes in their appearance even though their genetic composition is highly similar. These are gene polymorphisms that account for the change in the appearance of genetically similar organisms.

b.

Summary Introduction

To determine: The progeny and proportions predicted in octads from the cross with a mutation in nic3 located in chromosome 6.   

Introduction. The genes are the sequence of nucleotides that are present on the chromosomes and encode for a specific protein that plays a crucial role in the functioning of the different processes in an organism. The gene is located at specific gene loci and can be structural or regulatory in nature
