WebNov 1, 2009 · Abstract. Darwin's theory of natural selection lacked an adequate account of inheritance, making it logically incomplete. We review the interaction between evolution and genetics, showing how, unlike Mendel, Darwin's lack of a model of the mechanism of inheritance left him unable to interpret his own data that showed Mendelian ratios, even … Weba hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian …
