- Using the forked-line, or branch diagram, method, determine the genotypic and phenotypic ratios of these trihybrid crosses: (a) AaBbCc * AaBBCC, (b) AaBBCc * aaBBCc, and (c) AaBbCc * AaBbCc.Given the allelic frequency of A = .5 , answer the following 1. What is the homozygous dominant frequency ? 2. What is the allellc of a? 3. What is the heterozygous frequency ?Using a Punnet square complete the cross AABBCC and AaBbCc. Provide the genotypic and phenotypic ratio.
- Give only typing answer with explanation and conclusion The expected phenotype ratio in the F2 offspring of a monohybrid (F1 X F1) cross is ……? and the expected genotype ratio is …….? .Using the HardyWeinberg Law in Human Genetics Suppose you are monitoring the allelic and genotypic frequencies of the MN blood group locus (see Question 2 for a description of the MN blood group) in a small human population. You find that for 1-year-old children, the genotypic frequencies are MM = 0.25, MN = 0.5, and NN = 0.25, whereas the genotypic frequencies for adults are MM = 0.3, MN = 0.4, and NN = 0.3. a. Compute the M and N allele frequencies for 1-year-olds and adults. b. Are the allele frequencies in equilibrium in this population? c. Are the genotypic frequencies in equilibrium?Calculate the Chi square for cross 1 and cross 2 from the data in the attached image.
