Solution(By Examveda Team)
a. Genotype and phenotype is the term proposed by Johannsen. Wilhelm Johannsen first proposed the distinction between genotype and phenotype in the study of heredity while working in Denmark in 1909.b. Heterosis is the term given by Shull in 1914. Heterosis, or hybrid vigor, is the improved or increased function of any biological quality in a hybrid offspring.
c. Recurrent selection is proposed by Hull in 1945. Recurrent selection (Hull, 1945a) was meant to include reselection generation after generation, with the interbreeding of selects to provide for genetic recombination.
d. Over-dominance is proposed by Hull in 1945. The overdominance hypothesis postulates that heterosis is due to the superiority per se of heterozygous genotype compared to either parental homozygous genotype at individual loci.
