Answer #1

Answer:

A= 0.59

a = 0.41

Explanation:

AA = 0.3*0.3 = 0.09

Aa = 2*0.3*0.7 = 0.42

aa = 0.7 * 0.7 = 0.49 (will die)

After one generation…

AA = 0.09 = 2*0.09 = 0.18 of allele”A” frequency

Aa = 0.42 = 0.42 “A” and 0.42 “a” allele frequency

Total alleles frequency = 0.18 + 0.42 +0.42 = 1.02

Total A allele frequency = 0.18 + 0.42 = 0.6

Frequency of A allele = 0.6 / 1.02 = 0.59

Total a allele frequency = 0.42

    2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...

    Can anyone help me with these questions please? Thanks. 1. How do the allele frequencies compare across generations? Do they change much or do they remain fairly constant? Briefly explain why this might be, and also briefly explain how different the pattern would be if the population were much larger. 2. In generation 3, strong assortative mating was imposed. Using data for the whole class, evaluate the hypothesis that generation 3 was in HWE using statistical analysis. Discuss the effects...

    In gerbils there is a recessive mutant gene that causes a lethal condition. For the purpose of this problem let the symbol A denote the normal allele and a the mutant. In heterozygote individuals who carry both versions of the allele (Aa), this causes a white spotting color pattern. Homozygotes for the mutant (aa) die as embryos and are never seen in live gerbils. Since the mutant allele is lethal in the homozygous form, natural selection will occur against the...

    Please show how to works with type. Thank you. Gene Frequencies We will let p designate the frequency (=proportion) of gene B in a population, and we will let q designate the frequency of gene b. Since these are the only two alleles for that characteristic, then p + q = 1. (When all possible outcome frequencies are added, the sum of their frequencies must equal one (certainty)]. Now let us assume that completely random mating and offspring survival occurs...

    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):...
