After World War II, the allele frequency for brown eyes was B=0.4 and blue eyes b=0.6 The phenotype frequency in the US currently is brown = B 83% and blue b=17% Has the US population evolved with respect to eye color? Please help me understand what this question is asking? Do I need to use the Weinberg equation if so, please solve so I can see how to explain the answer?

Case B: In this population, the frequency of the dominant allele, B, is 0.5 and the frequency of the recessive allele, b, is 0.5. However, in this situation any individual who is born with the dominant trait has a 50 % chance of not surviving to reproductive age. Assuming that mating is still random, what will happen to the allele frequencies (p and q) after 5 generations? (le. Will one allele increase or decrease?) Prediction (1 mark): Reason (2 marks):...

ABO Blood Type allele frequencies: [I^O] = 0.7 , [I^A] = 0.2 , [I^B] = 0.1 For the Rh factor frequencies: [Rh+] = 0.8 , [Rh-] = 0.2 1. In this population what is the frequency of the type "O", Rh positive individuals? 2. The rarest type of blood is type AB Rh negative. How many of these are expected in 1000 individuals? 3.

In a population of jaguars, a gene with two alleles encodes the fur color. Allele B causes melanism (dark fur) and is dominant over allele b, which results in light colored fur. There has been a rare immigration event into a population of jaguars under study, resulting in the following genotype frequencies: 60% BB, 20% Bb and 20% bb individuals. If we assume HardyWeinberg equilibrium for future generations, what would be the genotype frequencies after 5 generations?

4. In the human population there is a recessive allele, d, that results in both polydactylism and dwarfism. The Amish are a small religious denomination founded in Switzerland in 1693. The incidence of the allele "d" in the Amish population is higher as compared with the greater human population. Studies have revealed that the original Swiss Amish population consisted of 10,000 individuals; 8100 with DD genotype, 1800 with Dd genotype, and 100 with dd genotype. Assuming this population is in...

In a population of mosquitos living in my backyard, I genotyped a representative sample of 100 at the buzz gene which has two alleles, B and b. Each copy of B makes the mosquito louder. Of my sample, 20 individuals are genotype BB (loud buzz), 40 are Bb (weak buzz) and 40 are bb (silent). A) What is the frequency of the b allele? B) What is the observed frequency of the Bb genotype? C) What is the Hardy-Weinberg Equilibrium...

4. In a given population, 16% of the population has blue eyes and 84% has brown eyes. Although eye color is a polygenic trait, let us assume for this problem that the brown-eyed allele is dominant to the blue-eyed allele and that the population is in Hardy-Weinberg equilibrium. What are the gene frequencies for brown eyed and blue-eyed alleles? = '16 Pa Brown-eyed allele frequency: _ qe 0.4 Pa 0.4 Blue-eyed allele frequency: - In this same population, there are...
