Which of the following would have caused Mendel to observe patterns of inheritance that supported the model of blending inheritance rather than transmission of alleles causing discrete differences?
Comments: Mendel's observations of segregation, and subsequently independent assortment, were possible because he was observing traits with clear and discrete binary phenotypes caused by discrete alleles of single genes. When multiple genes influence traits, or multiple alleles are present, intermediate phenotypes are likely to occur. (As a note, all traits are affected by genotype and the environment, but the extent of environmental influence was minimized in Mendel's methods that involved observing plants raised in a single garden under very similar environmental conditions, thereby minimizing variation caused by fluctuations in the environment.) A. Mendel chose traits controlled by more than a single gene. B. Mendel chose traits controlled by a single gene, but that gene had more than two alleles affecting the phenotype. C. Mendel chose traits affected by both the genotype and the environment. D. All of the answer options are all correct.
