Document Summary
Characteristics of dominant alleles: determines the phenotype of an organism, dominance depend on what other allele it is paired with. Since the black allele is always on the amp levels are always high: therefore the black allele is dominate because it determines the phenotype. Allele frequencies (p and q), given genotypic frequencies. 60% bearing brown allele (w) and 40% bearing the red allele (r: ww (6x6=36) wr (6x4=24) rw (4x6=24) rr (4x4=16) Function of various mc1r alleles: membrane receptor alleles, high cyclic amp cells melanocytes produce black melanin. Conditions necessary for hardy-weinberg equilibrium: no mutations are occurring, the population is closed to migration from other populations (gene flow, the population is infinite in size (large, all genotypes in the population survive and reproduce equally well. Individuals in the population mate randomly with respect to genotypes. Whether a population is in hwe, given observed genotype or phenotype frequencies. If genotype frequencies can be predicted from allele frequencies = hwe.
