The observation that populations from one region cannot mate with populations from another region (japan with. _____________________________ (4 pts) mother mother father father r = r = . Blending inheritance was a major stumbling block for the maintenance of genetic variation and darwin"s theory of evolution via natural selection. The following example will reinforce how our knowledge of inheritance eliminates this stumbling block. A white flowered, small flowered individual is crossed with a red flowered individual having large flowers and gives rise to offspring that are pink flowered and produce intermediate sized flowers. Given that aa and aa refers to the homozygous conditions of white and red, respectively and bb and bb refers to small and large flowered individuals, respectively, Provide the genotype of the pink intermediate sized flower individual (1 pt) and list (4 pts) the gametes produced by the pink, intermediate sized flowers for these two loci.
