Multiple Choice
Which of the following is the correct definition of the Hardy-Weinberg principle in the context of population genetics?
A
It states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences.
B
It explains the mechanism of chemical reactions in organic compounds.
C
It is a principle that defines the energy changes in chemical reactions.
D
It describes the process by which organisms with favorable traits are more likely to reproduce.
Verified step by step guidance
1
Identify the context of the Hardy-Weinberg principle, which is related to population genetics, not organic chemistry.
Understand that the Hardy-Weinberg principle is a fundamental concept in population genetics that describes how allele and genotype frequencies remain constant in a population under certain conditions.
Recognize that the principle assumes no evolutionary influences such as mutation, migration, genetic drift, or natural selection are acting on the population.
Differentiate between the options given: the correct definition involves allele and genotype frequencies, while the other options relate to chemical reactions and natural selection.
Conclude that the correct definition of the Hardy-Weinberg principle is that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences.
