We want to see if allele distributions change from generation to generation. We will use the Hardy Weinberg equations to find out. Due to migration and random mating of the parent generation, the percentage of homozygous recessive genotypes in Generation 2 offspring increases, changing_"a" to 40%, so a = 40 If "a" = .40, and "a"=q, then q = $ Remember that p + q = 1.0 If q, then p must = How many of these 50 offspring are homozygous dominant, heterozygous, or homozygous recessive? p² + 2pq+q²=…
r-Weinberg Equilibrium Problem Albinism is a rare genetically inherited trait that is only expressed in the phenotype of homozygous recessive individuals (aa) The most characteristic symptom is a marked deficiency in the skin and hair pigment melanin. This condition can occur among any human group as well as among other animal species. The average human frequency of albinism in North America is only about 5 in 100,00. What are the allelic frequencies of a and A in the North American population if this population is in Hardy-Weinberg equilibrium? What are the frequencies of each of the three possible genotypes in the North American population if this population is in Hardy-Weinberg equilibrium?

In sweet pea plants, an allele for purple flowers. (P) is dominanl when paired with a recessive allele for red flowers (p). An allele for Jang pollen grains (L) is dominant when paired with a recessive allele for round pollen grains (L). Bateson and Punnett crossed a plant having purple flowers and long pollen grains with one having white flowers and round pollen grains. All F1 offspring have purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple /lower/ round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
