About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness. a) What percentage of women would be expected to be colour blind? b) What percentage of women would be expected to be heterozygous? c) What percentage of men would be colour blind in the next generation?

A wild-type fruit fly (heterozygous for gray body color and red eyes) is mated with a black fruit fly with purple eyes. The offspring are wildtype, 721; black purple, 751; gray purple, 49; black red, 45. What is the recombination frequency between these genes for body color and eye color? Using information from problem 3, what fruit flies (genotypes and phenotypes) would you mate to determine the order of the body color, wing size, and eye color genes on the chromosome?
What is the frequency of the heterozygous genotype if the homozygous genotype frequencies are 0.1385 (BB) and 0.5897 (bb)?
20. 20.Which among the following statements is INCORRECT? A. Codominance is evident when a cross between organisms with two different phenotypes produces offspring that exhibits both parental traits because the alleles for each trait are neither completely dominant nor recessive B. Incomplete dominance is evident when a cross between a white carnation and a red carnation results in a pink carnation flower. C. Law of dominance state that if the alleles of a specific gene differ from each other, only one phenotype will be expressed while the other is masked D. The inheritance of one trait does not affect the inheritance of the other trait especially if the allele of the other trait is located in a different chromosome
For the fish model organism Medaka (Aplocheilus latipes), genes at 2 loci (B, b and R, r) determine color of the fish. Fish that have the dominant allele at both loci (B_ R_) are brown, fish with a dominant allele at the B locus (B_ rr) are blue, fish with a dominant allele at the R locus only (bb R_) are red, and fish that are homozygous recessive at both loci (bb rr) are white. What is the expected phenotypic ratio of offspring of cross between a homozygous brown and homozygous white Medaka fish? What is the expected phenotypic ratio of offspring if you then generate an F2 generations from the progeny above? Assume that you performed the cross and you observed 465 brown fish, 142 blue fish, 165 red fish, and 61 white fish in the F2 generation. Use a chi-square test to compare the observed and expected numbers of offspring. What conclusions can you draw from your statistical analysis of these results?
1) If TT is mated with Tt, how many of the offspring will genotypically turn out as tt? 2) If TT is mated with Tt, how many of the offspring will phenotypically turn out as t ?
Which of the following statements is/are false regarding alleles? (Select all correct answers.) For a given species, every gene has only two alleles All disease causing alleles are recessive to the wild-type allele A single allele can be recessive to the wild-type allele for one phenotype, but dominant to the wild-type allele for a different phenotype. For any pair of alleles of a given gene, the same dominant/recessive relationship will be found for all phenotypes affected by that gene
In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh-positive phenotype is produced by a dominant gene (A), and the Rh-negative phenotype is due to its recessive allele (a), what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive?
The Soay sheep of St. Kilda Island near Scotland have changed coat color over the past 20 years, with dark colored sheep declining in frequency and light colored sheep increasing. Coat color is determined by the TYRP1 gene. The TYRP1-T homozygote is light colored, while TYRP1-G homozygotes and heterozygotes are dark. Discuss the hypothesis that assortative mating between sheep with similar coat color is the cause of the increase in light coat color over this period.
