Questions 1-3 refer to the pedigree below that represents the presence of PTC tasting in a D.C. area family. PTC tasting is inherited through a dominant allele (T). The genotype of person #1 is: O a. TT O b.Tt O C.T? O d.tt O e.?t

A. What does it mean if an allele is “fixed”?  B. Explain one reason why EVEN if an allele is undergoing strong positive selection it may not become fixed in the population.

Please help with the following: Lactase persistence is an adaptation to milk drinking that has developed since the beginning of agriculture ~10 KYA. What is the relationship between the alleles driving this ability in European, Indian and African populations? A. One allele is responsible for lactase persistence in Europeans and Indians because of where agriculture originated and was introduced through migration. routes. B. The allele responsible for lactase persistence in all three populations is the same allele on the LCT gene. C. Different alleles are responsible for lactase persistence in each population. D. One allele is responsible for lactase persistence in Europeans, but other alleles cause the trait in Indian and African populations. E. One allele is responsible for lactase persistence in Africans, but other alleles cause the trait in European and Indian populations.
