Sure, let's address the question about how different alleles produced by mutation cause phenotypic variance in a population.

Answer
Different alleles produced by mutation cause phenotypic variance in a population by altering the genetic makeup at specific loci, which can lead to variations in traits.
Solution
a
Mutation: Mutations introduce new alleles into a population by altering the DNA sequence at a specific locus. These changes can be beneficial, neutral, or harmful
b
Allele Frequency: The frequency of different alleles in a population can change over time due to natural selection, genetic drift, gene flow, and mutation
c
Phenotypic Variance: The presence of multiple alleles at a locus can result in different phenotypes, as the alleles may encode for different versions of a protein or enzyme, leading to observable variations in traits
Key Concept
Alleles and Phenotypic Variance
Explanation
Mutations create new alleles, and the frequency of these alleles in a population can influence the range of phenotypes observed. This genetic diversity is crucial for evolution and adaptation.
