Allelism and Lethals

Presents examples of multiple allelism in man (ABO blood types), Drosophila (eye color and wing venation), rabbits (coat color), and tobacco (self-sterility). Discusses the way multiple alleles act to produce phenotypes. Indicates the classification of genes in accordance with their effects upon viability, some being detrimental and others lethal. Describes specific recessive lethals in the snapdragon, mouse, and horse. Lecture by Dr. C. Stern.
