Document Summary
Genetic variation mutations, gene flow and sex genotype the particular alleles at specified loci present in an organism. Mice like to store cotton and others that didn"t after 15 yrs of breeding you had a strong preference for and for not storing cotton scientific objection darwin didn"t understand where variation came from. Ronald fisher wrote genetical theory of natural selection, proved with math mendel and darwin compatible. 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. Bred fruit flies, and supported the the theory of chromosomal inheritance by finding that a specific gene is carried on a specific chromosome. 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.
