Answer #1

Answer:

The two alleles, taster and non-taster, persist in human populations over many generations is because these alleles have help humans in ensuring their survival and thus these are evolutionarily benefitting characteristics. Consumption of nutrients ensures the survival of organisms. But nutrient consumption through food can lead to death if toxic food is consumed. In most cases, toxic nutrients are bad tasting. Therefore the taster and non-taster alleles help in the distinction of that and help in the survival of humans and therefore, it has persisted over many generations.

    1. Fixation of Dominant Alleles Start with a population that has a gene with two alleles (A and a) with classical Mendelian dominance that are at equal frequency (p0.5. q 0.5). Assume this first generation is at hardy Weinberg equilibrium. Calculate the genotype frequencies AA- a. Aa b. Now assume some environmental change that makes the recessive phenotype completely unfit (fitness- 0). Calculate the allele frequencies and genotype frequencies in the second generation. (Hint: Your calculations might be easier if...

    Linkage Disequilibrium Mention one possible reason for why the level of LD in human populations is higher in Europe than in Africa? Mention one possible reason to why the level of LD is higher in dogs than in e.g. humans? Calculate LD between two biallelic loci in a situation where one haplotype is deleterious whereas the other haplotypes occur at equal frequencies. After how many generations have the LD between two loci with a recombination rate of 0.1 declined to...

    7. Why do dominant alleles tend to be advantageous and recessive alleles tend to be disadvantageous in most populations? 8. You are studying a population of parrots and you observe that there are two alleles for wing color. Allele 1 codes for green wings and is dominant over allele 2, which codes for red wings. Allele 2 is at a frequency of 70% of the population, what should be the frequency of allele 1 homozygotes? 9. You are studying a...

    You lead a research team that finds ​two non-migrating Southern Hemisphere populations​ of bunyips​ that are isolated from one another: one on a very cold island near Antarctica, and one on a tropical and very pleasant island near the equator. Through observation and experiments, you realize that ​cold tolerance​ is controlled by a single locus you uncreatively call ​cold​, with ​three alleles: ​A, a,​ and ​X​. You also find out that ​A​ mutates into either ​a​ or ​X​ at an...

    I did 1-5 but confused on the rest LAB EXERCISE 4.1 continued Name 6 Remember that the ability to taste PTC is dominant to the inability. Two normally pigmented taster parents have an albino, taster son and a non-taster daughter with normal pigmentation. Using A and Tand a and t for the dominant and recessive alleles, respectively, create a Punnett square for two traits, as shown on pages 71-73 in the section "Transmission of Autosomal Traits: Two at a Time."...
