Document Summary
Practice for test 1: in a population the frequency of a recessive allele is 30% what proportion of the population has the dominant trait. 30% = q p=1-q p=0. 7 (frequency of dominant allele) p2+2pq= 0. 72+2(0. 7)(0. 3) True-breeding means we are looking for p2 (homozygous) 1-0. 84=0. 16=q2 q= 0. 4(square root of 0. 16) p=1-q p=1-. 4. Since the hw predicts and observed are not the same that means they are not in equilibrium. 15 with genotype aa inbred means causing of homozygous frequency to increase and heterozygous to decrease: in pea plants axial flowers are dominant over terminal flowers. If an axial flower plant that is not truebreeding is crossed with a terminal flower plant that is truebreeding, what will be the ratios in the f1 offspring? genotype. A a in the f1 generation there is a 1:1. Aa: in pea plants inflated pods are dominant over constricted pods, and tall plants are dominant over dwarf plants.
