In a population, which allele is typically more common?
A
Dominant allele
B
Recessive allele
C
Allele with the highest frequency
D
Allele with the lowest frequency
Verified step by step guidance1
Understand that an allele's frequency in a population is determined by how often it appears in the gene pool, not by whether it is dominant or recessive.
Recognize that a dominant allele is one that expresses its trait even if only one copy is present, while a recessive allele requires two copies to express its trait.
Consider that the frequency of an allele is influenced by various factors such as natural selection, genetic drift, mutation, and gene flow, rather than its dominance or recessiveness.
Identify that the allele with the highest frequency is the one that appears most often in the population, regardless of whether it is dominant or recessive.
Conclude that the most common allele in a population is the one with the highest frequency, which can be either dominant or recessive depending on the specific genetic and environmental context.
