- What variable in the Hardy-Weinberg equation expresses the heterozygous genotype? A. p^2 + q^2 B. q^2 C. p^2 D. 2pqSickle Cell Anemia affects blood types in humans and represents what type of relationship compared to normal alleles? 1.Codominance 2.Incomplete Dominance 3.Epistasis 4.Dominant Lethal 5. It is not clear and could be 1 or 2How many different genotypes will be expected from a testcross of an individual with the genotype A/a; B/B; D/d; E/e; f/f? 64 8 16 81 27
- What is the predicted phenotypic ratio for the offspring of the following cross? Allele phenotypes: R = red, r = white, T = thin leaf, t = broad leaf Cross: RR; Tt x Rr; tt Red with thin leaves ___________ Red with broad leaves ___________ White with thin leaves ___________ White with broad leaves __________ PLEASE show work and give an explanation... Thank you!I don't really understand how to solve this question. For part a, I think my approach would be to find the genotypes of the parents first, and find the genotype of the F1. For part B, I would like to get some clarifications on the difference between linked genes with no crossing over vs. unlinked genes when approaching Punnett square type questions. Thank you also answer part a and b. Location of genetic markers is facilitated by physical mapping on the basis of the frequency of recombination.a) Trueb) False
