Detailed explanation-1: -Which condition would most likely result in an increase in the phenotypic variation within a population? A mutation leads to individuals with genetic differences.
Detailed explanation-2: -Two types of factors are recognized as contributing to the phenotypic variation in a population, genetic and environmental.
Detailed explanation-3: -Mutations can arise when mistakes are made while cells are copying DNA, like making a spelling mistake when copying a word. These mutations make up a species’ genetic diversity. Over generations, more and more mistakes are made, leading to more mutations.
Detailed explanation-4: -Errors in DNA replication generate genetic mutations, while errors in transcription and translation lead to phenotypic mutations.
