The statement that does not align with Mendel's hypotheses is:
B any organism that "shows" a heritable factor must be homozygous.
Mendel's findings indicated that an organism can be heterozygous (having one dominant and one recessive allele) and still display the dominant trait. Thus, it is not true that an organism showing a heritable factor must be homozygous; it can be either homozygous or heterozygous.
