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.

Sure, let me elaborate further. The Hardy-Weinberg equilibrium is a model that predicts the distribution of genotypes in a population that is...
