5. The color of the hull in oat seeds are determined by two genes that independently assort. The black hull phenotype is due to a dominant allele A. The grey hull phenotype is due to a dominant allele B. However, the effect of B is only apparent in the aa genotypes. In other words, the presence of the A allele masks the effect of the genotypes in the B gene. If neither A or B is present, the color of the hull would be white. You take a true breeding white strain (aabb) and cross it with a true breeding black strain (AABB). You let the F1 generation self-fertilize and collected the F2 generation of seeds. a. In the diagram below, please fill out the blue areas. In the rectangles, please fill in genotypes. In the parentheses, fill in proportions of respective genotypes. In the lines, specify the respective phenotypes (black, grey or white).. b. Out of all the black hulled seeds, what proportions have the genotype AaBb? Please show all calculations.. your PO F1 F2 ( A_B_ AABB ( aaB ( ) ( A_bb aabb ) aabb

The color of chickens is determined by interacting loci: AA or Aa give white, aaBB or aaBb give colored, and aabb produce white. Describe the epistatic interactions occurring between these two genes: A. aa is epistatic to B_, bb and bb are epistatic to A_,aa B. A_ is epistatic to B_,bb and bb is epistatic to A_,aa C. None of the above

5. Flower color in snapdragons is inherited in an incompletely dominant manner. Assume that RR = red flowers, Rr = pink flowers, and rr = white flowers. What would be the genotype and phenotype ratios of the offspring of two plants with pink flowers?

1. In fruit flies, the phenotype for eye color is determined by a certain locus. E indicates the dominant allele and eindicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit flyproduced the following offspring.Wild-typeMaleWild-typeFemaleWhite-eyedMaleWhite-eyedFemaleBrown-eyedFemaleF1 0 45 55 0 1The wild-type and white-eyed individuals from the F1 generation were then crossed to produce the followingoffspring.F2 23 31 22 24 0(a) Determine the genotypes of the original parents (P generation) and explain your reasoning. You may usePunnett squares to enhance your description, but the results from the Punnett squares must be discussed inyour answer.(b) Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes. Showall your work and explain the importance of your final answer.(c) The brown-eyed female in the F1 generation resulted from a mutational change. Explain what a mutation is,and discuss…
