Chapter 27: Problem 5

The term polymorphism can refer to both genes and traits. Explain what is meant by a polymorphic gene and a polymorphic trait. If a gene is polymorphic, does the trait that the gene affects also have to be polymorphic? Explain why or why not.

Short Answer

Expert verified
A polymorphic gene is one that is present in two or more forms due to mutation. A polymorphic trait is a trait that manifests differently in different individuals. The polymorphism of a gene does not necessarily mean that the trait it affects will also be polymorphic, as gene expression and thus trait manifestation can be influenced by other genes and environmental factors.

Step by step solution

01

Define Polymorphic Gene

A polymorphic gene is a gene that exists in two or more forms, or alleles. This variation is due to mutation in the DNA sequence of the gene.
02

Define Polymorphic Trait

A polymorphic trait is a trait that appears differently in different individuals. A single trait that appears in two or more forms is considered polymorphic.
03

Explain Relationship between Polymorphic Gene and Trait

A polymorphic gene does not necessitate that the trait it affects must also be polymorphic. The expression of a gene, which leads to a particular trait, can be influenced by many factors including other genes, an individual鈥檚 environment and a combination of both. So, a polymorphic gene may or may not result in a polymorphic trait.

Describe what happens to allele frequencies as a result of the bottleneck effect. Discuss the relevance of this effect with regard to species that are approaching extinction.

Cystic fibrosis (CF) is a recessive autosomal disorder. In certain populations of Northern European descent, the number of people born with this disorder is about 1 in 2500. Assuming HardyWeinberg equilibrium for this trait: A. What are the frequencies for the normal and \(\mathrm{CF}\) alleles? B. What are the genotype frequencies of homozygous normal, heterozygous, and homozygous affected individuals? C. Assuming random mating, what is the probability that two phenotypically unaffected heterozygous carriers will choose each other as mates?

In a population, the frequencies of two alleles are \(B=0.67\) and \(b=\) \(0.33\). The genotype frequencies are \(B B=0.50, B b=0.37\), and \(b b=\) \(0.13\). Do these numbers suggest inbreeding? Explain why or why not.

In genetics, what does the term population mean? Pick any species you like and describe how its population might change over the course of many generations.

Antibiotics are commonly used to combat bacterial and fungal infections. During the past several decades, however, antibioticresistant strains of microorganisms have become alarmingly prevalent. This has undermined the effectiveness of antibiotics in treating many types of infectious disease. Discuss how the following processes that alter allele frequencies may have contributed to the emergence of antibiotic-resistant strains: A. Random mutation B. Genetic drift C. Natural selection
