Mendelian Genetics Lab Practice Mendelian Genetics Lab Practice Genetic Crosses That Involve TWO Characters Note: In rabbita, grey hair la dominant to white hair. Also in rabbits, black eyes are dominant to red eyes. 3. A male rabbit with the genotype GABA is crossed with a female rabbit with the genotype Gabb The square is set up below. Fit out and determine the phenotypes and proportions the offspring GG and Gg-grey hair 99 - white hair • How many out...
please include work, show punnets squares and legends. thanks 2. A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is x-linked recessive, W+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, and half of the male and half of the female offspring were white-eyed. What was the genotype of the female fly?
A (w-/ w-) white-eyed Drosophila female is crossed with a red-eyed male. Assuming the trait for eye color is sex-linked, what are the possible phenotypes of the progeny? All red-eyed individuals Red- and white-eyed females and males Only red-eyed females and white-eyed males Both red- and white-eyed males and only white-eyed females None of these
5. Show the cross of a red eyed female (heterozygous) and a red eyed male What are the genotypes of the parents? How many of the offspring are white eyed, male white eyed, female red eyed, male red eyed, female 6. In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but theywon'tever be carriers) XHXH=female, non-hemophilic X H X h female, carrier Xh Xh-...
A female Drosophila melanogaster is crossed with a male. The male's phenotype and genotype are unknown, while female's phenotype is known to be red eyes, straight wings, shaved bristles, and an ebony body. So, then the female's genotype should be Xw+Xw ; c+ c; ee; sdsd. Given that red eyes are dominant to white eyes, straight wings are dominant to curved wings, long bristles are dominant to shaven bristles, and a gray body is dominant to an ebony, draw a...
7. A female calico cat is crossed with a male black cat. What are the phenotypes of the offspring? 8. Also located on the X chromosome of a cat is a gene that codes for deafness. This gene is recessive. A female cat that is heterozygous for deafness is crossed with a male cat that is not deaf. What are the genotypes and phenotypes of the offspring? (use the letter "D" for hearing)
2. A white eyed female fly (w is a recessive allele of a gene for eye pigmentation on the X chromosome) is crossed with a red eyed male fly. a. Give the genotypes for the parental generation. b. Give the phenotypes and genotypes, and their proportions, for the F1 generation. c.Fls are crossed to one another. Give the phenotypes and genotypes, and their proportions, for the F2 generation.
29, In fruit flies, red eyes are dominant over white eyes. The gene for eye color (R) is found on the X chromosome (X^R). Females have 2 X chromosomes and males are XY. Fill in the following (case sensitive!): Genotype of a white eyed female: Possible female gametes; separate gametes with a comma (,): Genotype of a red eyed male: Possible male gametes; separate gametes with a comma (,): In fruit flies, red eyes are dominant over white eyes. The...
Questions 64-65 refer to the following. In a plant, axial flower (T) is dominant to terminal flower (t) and red fruit color (Y) is dominant to yellow (y). These effects are caused by two independently assorting autosomal genes. An individual terminal red plant was crossed with an individual axial, yellow plant to produce offspring which were 1/2 axial, red: 1/2 terminal, red. The genotype of the crossed terminal red plant was: ttyy ttYy ttYY TTyy Ttyy In the cross described...
