- 75. Under the conditions of the Hardy-Weinberg equilibrium, what term in the equilibrium equation represents the expected genotype frequency for homozygous recessive individuals? p2 2pq 2p+q p2+2pq+q2 q2Question 1 A. What conclusions can you draw concerning the paternity of Puppy #2? Please explain. B. What are the drawbacks to the use of DNA fingerprinting in court?1. In humans, widow’s peak (W) is dominant over having a straight hairline (w). If a homozygous man with a widow’s peak has a child with a woman with a straight hairline, what are the odds the child will have a widow’s peak? Show work. 2. Ellis-van Creveld syndrome is a recessive inherited condition that results in 6-fingered dwarfism. Two parents without this condition have with Ellis-van Creveld syndrome. What are the genotypes of the parents and offspring? What are the odds that the son will have a 6-fingered child if his partner is a woman who is heterozygous for the condition? Show work. 3. The gene for dangling earlobes is dominant over the gene for attached earlobes. A woman with attached earlobes has a child with a man with dangling earlobes whose mother had attached earlobes. What is the probability that this child will have attached lobes? Show work. 4. In humans, normal pigmentation is due to a dominant gene, while albinism is recessive. A normally pigmented man has a…
- Why is it more efficient to perform a test cross with a homozygous recessive donor than a homozygous dominant donor? How could the same information still he found with a homozygous dominant donor?1. Briefly discuss the Genetic parameters for selecting process 2. Briefly discuss the Values and variance components mentioned in https://www.researchgate.net/publication/235324145_Quantitative_Genetic_Application_in_the_Selection_Process_for_Livestock_Production33. In humans, the presence of chin and cheek dimples is dominant to the absence of dimples, and the ability to taste the compound PTC is dominant to the inability to taste the compound. Both traits are autosomal, and they are unlinked. The frequencies of alleles for dimples are D=0.62 and d=0.38. For tasting, the allele frequencies are T= 0.76 and t= 0.24 Determine the frequency of genotypes for each gene and the frequency of each phenotype. What are the expected frequencies of the four possible phenotype combinations: dimpled tasters; undimpled tasters, dimpled non-tasters, and undimpled non-tasters?
