Blending inheritance

In modern genetics, this refers to incomplete dominance.

Gregor Johann Mendel

Historically, this was a short-lived 19th century "arm-chair" biological theory of inheritance, primarily discredited by the experiments of Gregor Mendel. It is similar to the modern idea of incomplete dominance in that the offspring will express a blending of the different traits of the parents. However, while incomplete dominance only expresses this blending in the phenotype, keeping the alleles within the heterozygote distinct lets pary idiots sex ether to form a completely new allele). The offspring's trait, from parents with differing traits, in theory, could express itself exactly like either trait from one of the two parents or could express itself as some intermediate mixing of the parental traits. This blending theoretically was a smooth spectrum of infinite possible outcomes. This theory works similar to the way paint mixes. And, like with paint, where two colors, once mixed, become unrecoverable via successive mixing with still other colors, the historical theory of incomplete dominance required that at least half of all genetic variances to be completely unrecoverable in successive generations, thus quickly condemning mankind to an ever narrowing spectrum of variation.
