4. In Drosophila, eye color is determined by two different genes located on different chromosomes. A recessive gene b, found on the second chromosome, produces brown eye color. The second chromosome is an autosomal chromosome. A recessive sex-linked gene v causes vermilion eye color to be produced. The presence of the dominant genes B and V results in a wild-type color. The presence of both the brown and vermilion allele, in the homozygous condition result in an individual with white eyes. Indicate the genotypes and phenotypes produced from the following crosses: a) BBVV(wild-type female) x bbvY(white-eyed male) b) BbVv ( wild-type female) x BBVY (wild-type male) c) bbVV ( brown-eyed female) x BbvY (vermilion-eyed male)

17. In rats, the following genotypes of two independently assorting autosomal genes determine coat color.A_B_ (gray)A_bb (yellow)aaB_ (black)aabb (cream)A third gene pair on a separate autosome determines whether or not any color will be produced.The CC and Cc genotypes allow color according to the expression of the A and B alleles.However, the cc genotype results in albino rats regardless of the A and B alleles present. Given the inheritance pattern of coat color in rats described in Problem 17, predict the genotype and phenotype of the parents who produced the following offspring: (c) 27/64 gray: 16/64 albino: 9/64 yellow: 9/64 black: 3/64 cream
8. While vermilion is X-linked and brightens the eye color, brown is an autosomal recessive mutation that darkens the eye. Flies carrying both mutations lose all pigmentation and are white-eyed. Predict the Fl and F2 results of the following crosses: a) vermilion females X brown males b) brown females X vermilion males
. In Drosophila melanogaster many eye color mutations are known. One such recessive mutation is called brown (bw) and gives brown eyes instead of the wild type dark red eyes. Another recessive mutation is scarlet (st) which gives bright red eyes. The bw st double mutant has white eyes. A brown-eyed male was crossed to a scarlet- eyed female. The F1 progeny were wildtype. When the F1 males were test-crossed to bw/bw st/st females the following progeny phenotypes were produced: 1/4 wildtype, 1/4 brown, 1/4 scarlet, 1/4 white. These results show that the two genes are? Select all that apply a)linked and 25cM apart b)sex linked c)linked d)assorting independently Please answer asap and in short and content should not be palgarised please answer
3. A man who has polydactyly and normal vision marries a color-blind woman with a normal number of hand and foot digits. The man's father has normal hand and foot digitation, and both the woman's parents have normal hand and foot digitation. A) Polydactyly is autosomal dominant, which means [ Select ] the gene is carried on the X chromosome b. the gene is carried on a non-sex chromosome a. c. the gene is carried on the Y chromosome d. the dominant allele is actually recessive B) Red-green color blindness is X-linked recessive, which means that in females, [ Select ] a. the recessive allele is actually dominant b. the gene is carried on a non-sex chromosome c. the gene must have both recessive alleles to be expressed in the phenotype d. the gene is carried on the Y chromosome C) What proportion of their sons would be color blind and polydactyly?

1.In Drosophila melanogaster body color is controlled by one gene while wing shape is controlled by a second gene. Gray body color is dominant to black body color, and normal wings are dominant to vestigial wings. Flies homozygous for gray body color and vestigial wings are crossed with flies homozygous for black body color and normal wings. A.compare the possible f2 generation genotypes and phenotypes and proportions if these two traits. B.How does your answer change if one of the original parents is homozygous for gray body color and normal wings while the other has black body color and vestigial wings?
4. In cattle, polled (absence of horns) is dominant over horned and roan is the result of the heterozygous condition of the genes for red and white coat color. (Neither red nor white is dominant so in the heterozygote, both are expressed.) Assume both traits are on separate pairs of autosomes. What proportion of the offspring of a roan heterozygous polled bull and a roan horned cow would be expected to be roan and horned?
Part 1. Norrie disease is caused by a recessive mutation on the X chromosome in a gene called norrin. The disease affects the eyes and can cause blindness. In the picture below, the left (A) and right (B) retinas from the same female mouse are shown. The X chromosome inherited from the father is labeled magenta and the X chromosome inherited from the mother is labeled yellow. А. В. From this picture, and the information you know about X chromosomes, what can you conclude? Imprinting randomly renders one of these X chromosomes inactive per cell, so this is what you would expect from that process. The maternal chromosome is likely imprinted in the left eye while the paternal chromosome is likely imprinted in the right eye. In the left eye, more of the cells have the paternal chromosome inactivated than in the right eye. In the left eye, more of the cells have the maternal chromosome inactivated than in the right eye. Part 2. Given the information in the previous question, if the norrin…
8. In alley cats, the coat color is determined by a gene carried on the X chromosome. Genotypes and color are as follows: b X² Females: xbx=yellow xBxb = calico XBXB = black Males: xby = yellow x³y = black A calico cat has a litter of eight kittens: one yellow male, two black males, two yellow females, and three calico females. What is the color of the father of the litter?
4. In Drosophila melanogaster, a yellow-bodied (dark coloured) male with vestigial (underformed) wings is crossed to a wildtype female (brown body, red eyes). The F1 generation are all wildtypes. An F1 male and female are crossed and the F2 progeny consists of 16 vestigial-winged males with yellow bodies, 48 yellow males with normal wings, 15 males with vestigial wings and yellow bodies, 49 wildtype males, 31 vestigial winged females with brown bodies and 97 wildtype females. Explain the inheritance pattern of the 2 genes.
19) In Drosophila fruit flies, the gene controlling bristle length is X-linked. Wild type flies have long bristles; short bristles is a recessive trait. You cross a long-bristled female fly to a short-bristled male fly. All the F1 progeny have a wild type phenotype. Next, you cross the F1 flies to produce an F2 generation. If there are a total of 200 F2 flies, how many of the F2 females are expected to have short bristles? V/100 Wild type fruit flies have grey bodies and straight wings. Yellow bodies and curly wings are both recessive phenotypes. The body color gene is X-linked; the wild type allele is designated XY+. The wing shape gene is autosomal; the wild type allele is designated C+. You cross a pure breeding yellow-bodied, curly-winged female with a grey-bodied, straight-winged male to produce an F1 generation. Use this information to answer questions X-Y below. You cross two F1 flies to produce an F2 generation. You select a female F2 fly that is phenotypically wild type. What…
