In a randomly mating laboratory population of Drosophila, 4 percent of the flies have black bodies (encodedby the autosomal recessive b), and 96 percent havebrown bodies (the wild type, encoded by B). If this population is assumed to be in Hardy–Weinberg equilibrium, what are the allele frequencies of B and b and thegenotypic frequencies of B/B and B/b?
Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
Cystic fibrosis (CF) is a recessive autosomal disorder. In certain populations of Northern European descent, the number of people born with this disorder is about 1 in 2500. Assuming Hardy- Weinberg equilibrium for this trait: A. What are the frequencies for the normal and CF alleles? B. What are the genotype frequencies of homozygous normal, heterozygous, and homozygous affected individuals? C. Assuming random mating, what is the probability that two phenotypically unaffected heterozygous carriers will choose each other as mates?
In a randomly mating population of Drosophila, 16% of the flies have black bodies (an autosomal, recessive trait) and 84% have brown bodies. This population is assumed to be in Hardy-Weinberg equilibrium. 6. If a researcher samples 10 000 Drosophila from this population, the number of flies expected to be homozygous dominant for body colour is 8 400 1600 3 600 4 800 Congenital myasthenic syndrome (CMS) is an autosomal recessive disorder that is found in a higher-than-normal frequency in a Roma population in Europe. Researchers examined 43 people for CMS in the population and found that 13 of them had the disorder. 11. What is the frequency of the CMS disorder in the Roma population examined by the researchers? Answer: (Record your answer as a value rounded to two decimal places in the numerical-response section on the answer sheet.)

Color blindness in humans is an X-linked recessive trait. Approximately10% of the men in a particular population are color blind.a. If mating is random with respect to the color-blindness locus, what isthe frequency of the color-blindness allele in this population?b. What proportion of the women in this population are expected to becolor blind?c. What proportion of the women in this population are expected to beheterozygous carriers of the color-blindness allele?
In a population of Drosophila melanogaster reared in thelaboratory, the mean wing length is 0.55 mm and therange is 0.35 to 0.65. A geneticist selects a female withwings that are 0.42 mm in length and mates her with amale that has wings that are 0.56 mm in length.a. What is the expected wing length of their offspringif wing length has a narrow-sense heritability of 1.0?b. What is the expected wing length of their offspring ifwing length has a narrow-sense heritability of 0.0?

Explain why you need both the multiplication and addition rules to calculate the probability that an MN offspring will be produced in a human population The multiplication rule gives the probability that a particular mating will occur and that mating will produce the target genotype, and the addition rule gives the total probability of each target genotype, because the matings that produce the target genotype are mutually exclusive. The multiplication rule gives the probability that a particular mating will occur, and the addition rule gives the probability that the mating will produce the target genotype. The addition rule gives the probability that a particular mating will occur and that mating will produce the target genotype, and the multiplication rule gives the total probability of each target genotype. The multiplication rule gives the probability that a particular mating will produce the target genotype, and the addition rule gives the probability of obtaining the particular…
