Textbook Question
Chapter 5, Problem 1RQ
What is the relationship between homologous chromosomes, copies of a gene, and alleles?
Expert Solution & Answer
Summary Introduction
To explain: The relationship between homologous chromosomes, copies of a gene, and allele.
Introduction: Chromosomes are the large molecules of genes or DNA. The necessary information for every character of an organism is contained in the DNA. Combinations of thousands of these genetic molecules control the traits of an organism.
Explanation of Solution
Homologous chromosomes are paired chromosomes in a diploid organism. There are two sets of homologous chromosomes present in a diploid organism each set of chromosomes inherited from mother and father. Homologous chromosomes have a similar position of the centromere, location of gene, size and shape. There are two copies of each gene in homologous pairs of chromosomes; each copy received from both parents. Each gene of particular traits may have different variants which are known as alleles.

Problem 1 (Mental Health): The survivor victim is dealing with acute stress and symptoms of a
post-traumatic stress disorder (PTSD) due to their traumatic experience during the January 2025 wildfire.
Goal 1: To alleviate the client's overall level, frequency, and intensity of
anxiety and PTSD symptoms so that daily functioning remains
unimpaired.
Objective 1: The client will learn and regularly use at least two anxieties
management techniques to reduce anxiety symptoms to less than three episodes per week.
Intervention 1: The therapist will provide psychoeducation about anxiety and
PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.

A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant).

Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.
