- .Certain forms of human color blindness are inherited as X-linkedrecessive traits. Hemizygous males are color-blind, but heterozygous females are not. However, heterozygous females sometimeshave partial color blindness.A. Discuss why heterozygous females may have partial color blindness.B. Doctors identified an unusual case in which a heterozygousfemale was color-blind in her right eye but had normal colorvision in her left eye. Explain how this might have occurred.You have decided to cross your golden Labrador retriever (BBee) with the neighbor's chocolate retriever (bbEe). Gene B when dominant (B_) produces a black Labrador. Gene (E) when recessive is epistatic to the color locus and can inhibit pigment formation leading to the golden dog. What color pups will they have?In Drosophila, a heterozygous female for the X-linkedrecessive traits a, b, and c was crossed to a male that phenotypically expressed a, b, and c. The offspring occurred inthe following phenotypic ratios.+ b c 460a + + 450a b c 32+ + + 38a + c 11+ b + 9 No other phenotypes were observed.(a) What is the genotypic arrangement of the alleles ofthese genes on the X chromosome of the female?
- More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b. Parents: brown eyes, right-handed blue eyes, right-handed Offspring: 6/16 blue eyes, right-handed 2/16 blue eyes, left-handed 6/16 brown eyes, right-handed 2/16 brown eyes, left-handed c. Parents: brown eyes, right-handed blue eyes, left-handed Offspring: 1/4 brown eyes, right-handed 1/4 brown eyes, left-handed 1/4 blue eyes, right-handed 1/4 blue eyes, left-handedIn currant moths, their Light color is sex-linked and recessive (d) to dark color (D). Question: What are the genotype and the phenotype of the parents if a certain cross yields ½ dark and ½ light colored females and all dark males? Take note that female moths are heterogametic.In Drosophila, the vestigial wings recessive allele,vg, causes the wings to be very small. A geneticistcrossed some true-breeding wild-type males to some vestigial virgin females. The male and female F1 flieswere wild type. He then allowed the F1 flies to matewith one another and found that 1/4 of the male andfemale F2 flies had vestigial wings. He dumped thevestigial F2 flies into a morgue and allowed the wildtype F2 flies to mate and produce an F3 generation.a. Give the genotype and allele frequencies amongthe wild-type F2 flies.b. What will be the frequencies of wild-type andvestigial flies in the F3?c. Assuming the geneticist repeated the selection againstthe vestigial F3 flies (that is, he dumped them in amorgue and allowed the wild-type F3 flies to mate atrandom), what will be the frequency of the wild-typeand mutant alleles in the F4 generation?d. Now the geneticist lets all of the F4 flies mate atrandom (that is, both wild-type and vestigial fliesmate). What will be the…
- Red–green color blindness in humans is due to an X-linked recessive gene. A womanwhose father is color blind possesses one eye with normal color vision and one eye with colorblindness.(a) Propose an explanation for this woman’s vision pattern.(b) Would it be possible for a man to have one eye with normal color vision and one eye withcolor blindness?.Suppose that a gene affects the anterior morphology in house flies andis inherited as a maternal effect gene. The gene exists in a functionalallele, H, and a recessive nonfunctional allele, h, which causes a smallhead. A female fly with a normal head is mated to a true-breedingmale with a small head. All of the offspring have small heads. Whatare the genotypes of the mother and offspring? Explain your answerCarrion beetles lay their eggs in dead animals and then bury them in the ground until they hatch. Assume that the preference for fresh meat (F) is dominant to the preference for rotted meat and that the tendency to bury the meat shallow (S) is dominant to the tendency to bury the meat deep. Suppose a female carrion beetle homozygous dominant for both traits mates with a male homozygous recessive for both tra What will be the genotype of the F1 generation?

What offspring would you expect from(a) the cross of a barred hen to a nonbarred rooster?(b) the cross of an F1 rooster from part (a) to one ofhis sisters?In fruit flies, L = long wings and l = short wings. When a long-winged fly is crossed with a short-winged fly, the offspring exhibit a 50:50 phenotypic ratio. What is the genotype of the parent flies? Prove how this is possible. Develop a Punnett square, and then list the genotypes and phenotypes.Assume for a moment that you are working in a genetics lab with the fruit fly Drosophila melanogaster, a model organism for genetic research. You want to determine whether a newly found Drosophila characteristic is dominant or recessive.a. Explain how you would construct such a cross, as well as the expected outcomes that would indicate dominance.b. Why would working with Drosophila be easier than working with humans?
