Which of the following situations would have caused Mendel to observe patterns of inheritance that supported the model of blending inheritance instead of transmission of alleles causing discrete differences?
A)if Mendel chose traits controlled by more than a single gene
B)if Mendel chose traits controlled by a single gene, but that gene had more than two alleles affecting the phenotype
C)if Mendel chose traits affected by both the genotype and the environment
D)All of these choices are correct.

All of these situations could have led Mendel to observe patterns that seemed to support blending inheritance. A) Traits controlled by multiple genes often show a continuous range of variation rather than discrete categories, which could appear as blending. B) A single gene with multiple alleles can also produce a range of phenotypes, potentially mimicking blending. C) Environmental effects on phenotypic expression can blur the distinctions between genotypes, making inheritance appear to blend from one generation to the next.
