PSYCH-UA 25 Lecture Notes - Lecture 10: Ronald Fisher, Chromosome
Document Summary
Mendelian heredity contributed greatly to our knowledge of single gene pair inheritance. cross breeding strains of peas and observing outcomes. dominant and recessive gene discovery genotype the particular alleles at specified loci present in an organism. Bred fruit flies, and supported the the theory of chromosomal inheritance by finding that a specific gene is carried on a specific chromosome. Ronald fisher wrote genetical theory of natural selection, proved with math mendel and darwin compatible. Demonstrated mathematically that a mendelian pattern of inheritance is entirely consistent with a theory of gradual evolution based on natural selection. With mendelian inheritance there is no inherent tendency for variability to diminish over time.
