A lizard population has two alleles conferring different tolerance to heat stress. In stressful heat conditions, the following genotypes give on average the following number of offspring per reproductive season: Att/Atn = 3; Att/Att= 5; Atn/Atn = 11. If this lizard population has an initial frequency for the allele Att of 0.4, what will the frequency of Att be in the next generation under stressful heat conditions

QUESTION 10 A lizard population has two alleles conferring different tolerance to heat stress. In stressful heat conditions, the following genotypes give on average the following number of offspring per reproductive season: Att/Atn = 10; Att/Att=20; Atn/Atn = 3. If this lizard population has an initial frequency for the allele Att of 0.3, what will the frequency of Att be in the next generation under stressful heat conditions? 0.52 0.48 0 037 0.24

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

In the figure, p is the frequency of allele A, and is the frequency of allele a in a diploid population. Assuming no differences in fitness, pand should also be the frequencies of A gametes and a gametes produced by the adults. The A and a gametes combine during fertilization to produce diploid zygotes. If mating is random and the population is large, the proportion of offspring with each of three genotypes (AA, Aa, and aa) can be predicted using...

Calculate the amount of evolution in one generation for the following scenario for alleles A1 and A2 (p = frequency of A1): Initial allele frequencies: p = 0.4, q = 0.6 Fitness: W11 = 0.85, W12 = 1.00, W22=0.70 What are the genotype frequencies among juveniles at the beginning of this generation (assuming random mating in the previous generation)? What is the mean fitness of the population in this generation? What will be the allele frequencies in the next generation...

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...

In genetics, single nucleotide polymorphisms (SNPs) are locations in the (human) genome that exhibit variation across the population. SNPs cause the differences we see in traits such as hair color. Each SNP typically has two possible alleles say A and a and each person's genotype at the SNP is either AA, Aa, or aa, where one allele comes from the person's mother and one from the father. Let X be the number of A alleles at a particular SNP, and...
