What is the difference between genetic variation, environmental variation, and genotype-by-environment interaction? Give examples of each. Try to think of potential examples not covered in this chapter.

Expert Solution

Summary Introduction

To determine: The differences between genetic variation, environmental variation, and genotype-by-environment interaction.

Introduction: Genes are long thread-like structures that contain coded genetic information in the form of DNA. Deoxyribonucleic acid (DNA) is a double-stranded structure, and it is transferred from one generation to the next generation through successful reproduction.

Explanation of Solution

Criteria	Genetic variation	Environmental variation	Genotype-by-environment interaction
Definition	The variations in an individual that occur due to differences in nucleotide sequence present in DNA result in genetic variation.	The variations or adaptations that occur in an individual due to changes in the environment or external surroundings are known as environmental variation.	This type of variation occurs due to difference in the response of two different genotypes to a common environmental variation.

Students have asked these similar questions

In population genetics, for a locus with two alleles, we use the variable q to indicate. Freq(a), the frequency of the recessive allele Freq(Aa), the frequency of the Aa genotype Freq(AA), the frequency of the AA genotype Freq(A), the frequency of the dominant allele Freq(aa), the frequency of the aa genotype

Which of the following statements does NOT apply to the Hardy-Weinberg expression: p2 + 2pq + q2? Group of answer choices p2 is the frequency of individuals with the homozygous recessive genotype. 2pq is the frequency of individuals with the heterozygous genotype. It can be used to determine the genotype and allele frequencies of the previous and the next generations. Knowing either p2 or q2, you can calculate all the other frequencies

If 120 of 200 alleles are dominant alleles, then what percentage of the alleles are dominant alleles? A-12% B-40% C-60% D-120% What percentage of the alleles are recessive alleles? E-8% F-40% G-60% H-80% Which of the terms of the Hardy-Weinberg equations represents the frequency of the recessive allele in the gene pool? A-p^2 B-p C-2pq D-q^2
