How does the model support an explanation of how natural selection can lead to changes in a population?
The genotypic ratios in generation 2 do not conform to Hardy-Weinberg equilibrium; therefore, changes are occurring in the populat
which are caused by natural selection.
The genotype, R is the genotype for all plants in generation 3; therefore, plants with this genotype have a reproductive advantage o
other plants.
• The genotype, r is absent in generation 3; therefore, changes are occurring in the population which are caused by natural selection.
The genotypic ratios in generation 3 do not conform to Hardy-Weinberg equilibrium; therefore, changes are occurring in the populatic
which are caused by natural selection.
Answer
The genotypic ratios in generation 2 and 3 not conforming to Hardy-Weinberg equilibrium supports the explanation of how natural selection can lead to changes in a population. The absence of certain genotypes and the prevalence of others suggest that certain traits are being selected for or against, leading to changes in the population over time.
