Well, Mendel thought so, but it is not true. Condider dimples: They are controlled by a dominant gene, however, dimples are not very common. Why is this? The allele for dimples is rare, even if it is dominant. Dominant means it shows a genotype over a recessive gene, it has nothing to do with gene frequency.
