- Write the cross using correct symbols. What kind of cross is this called?
Step by step
Solved in 3 steps with 1 images
- In cats, the genotype AA produces tabby fur color; Aa is also a tabby, and aa is black. Another gene at a different locus is epistatic to the gene for fur color. When present in its dominant W form (WW or Ww), this gene blocks the formation of fur color and all the offspring are white; ww individuals develop normal fur color. What fur colors, and in what proportions, would you expect from the cross AaWw Aa Ww?1. You are given a female F1 of unknown genotype. You cross the female fly to a homozygous male that has forked bristles and malformed eyes. The offspring of the cross is shown below: (Define symbols for your traits) Phenotype Forked bristles, normal eyes 752 Number Genotype Forked bristles, malformed 56 eyes Malformed eyes, normal bristles Normal eyes, normal bristles 820 64 a. What are the genotypes of the offspring? b. Based on the progeny, what were the genotypes of the F1 parents? What is the distance between for and mal?1. The allele G for yellow stigma is completely dominant to green (g). Supposingtwo strains of autotetraploid plants are available and their genotypes are as follows:GGgg – in this plant the gene is close to the centromereGggg – in this plant the gene is far from the centromere If these two plants are crossed:a) provide the gametes that can be obtained from the two plants;b) provide the genotypic and phenotypic ratios of the offspring. 2. Consider the illustration below. Diagram the configuration you would observe at Anaphase I if crossing-over happens within the inversion. (IMAGE ATTACHED)
- 3. The allele b gives Drosophila flies a black body and b+ gives brown, the wild-type phenotype. The allele wx of a separate gene gives waxy wings and wx+ gives nonwaxy, the wild-type phenotype. The allele cn of a third gene gives cinnabar eyes and cn+ gives red, the wild-type phenotype. A female heterozygous for these three genes is testcrossed, and 1000 progeny are classified as follows: 5 wild type; 6 black, waxy, cinnabar; 69 waxy, cinnabar; 67 black; 382 cinnabar; 379 black, waxy; 48 waxy; and 44 black, cinnabar. Are these three genes linked? If so, draw a map of the chromosomes in the heterozygous parent, showing the order, arrangement, and map distance between the linked genes.2.) In fruit flies, L= long wings and 1= 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.15. B. You set up a cross between a male fruit fly with lobe eyes and a true breeding female fruit fly with reduced bristles and disrupted wings. In the F1 offspring you see the all the flies have WT bristles and WT wings. However, half the flies have WT eyes and half the flies have lobe eyes. You take 20 of the F1 female flies with lobe eyes and mate them to 20 true breeding male flies with reduced bristles and disrupted wings and observe the following offspring: 164 lobe eyes and reduced bristles 137 lobe eyes and disrupted wings 638 reduced bristles and disrupted wings 152 reduced bristles 40 wildtype 175 disrupted wings 659 lobe eyes 35 lobe eyes reduced bristles and disrupted wings Calculate the interference for this region.
- 2. In Drosophila sp. Red eyes are dominant over white eyes. Normal wings are dominant over vestigial wings. Homozygous red eyes normal wings females were crossed with homozygous white eyes and vestigial wings males. The F2 generation after a test cross are as below Phenotype Red eyes, normal wings White eyes, vestigial wings Red eyes, vestigial wings White eyes, normal wings Amount 1670 1590 425 435 a) Are the wings and eyes colour genes linked? b) Show all the crosses c) Calculate the recombination frequency value. d) What is the distance between the wings and eyes colour genes?14. A wildtype fruit fly (heterozygous for gray body and normal wings) is mated 2 poin with a black fly with vestigial wings. Offspring: 778-wild type 785-black vestigial 158-black-normal wings 162 gray body-vestigial wings. 1. What is the recombination frequency between these genes? 2. Are the genes linked? Explain why or why not. *3. What is the genotypic ratio of the testcross shown in Figure 4? 4. Give the phenotypic and genotypic ratio of the following testcrosses of dihybrids: Cross A Cross B P ΥY RR yy rr P YY Rr yy rr F1 F, YR Yy Rr YR Үy Rr (Y Yy rr Cross C Cross D P.

- 0. In Drosophila, the gene for cinnabar eye color is onchromosome 2, and the gene for scarlet eye color is onchromosome 3. A fly homozygous for both recessivecinnabar and scarlet alleles (cn/cn; st/st) is white-eyed.a. If male flies (containing chromosomes with thenormal gene order) heterozygous for cn and st allelesare crossed to white-eyed females homozygous forthe cn and st alleles, what are the expected phenotypes and their frequencies in the progeny?b. One unusual male heterozygous for cn and st alleles,when crossed to a white-eyed female, produced onlywild-type and white-eyed progeny. Explain the likelychromosomal constitution of this male.c. When the wild-type F1 females from the cross withthe unusual male were backcrossed to normal cn/cn;st/st males, the following results were obtained:wild type 45%cinnabar 5%scarlet 5%white 45%Diagram a genetic event at metaphase I that couldproduce the rare cinnabar or scarlet flies among theprogeny of the wild-type F1 females.IV. Other dihybrid cross Gene symbols v vestigial wing size V normal wing size s sepia eye color S red eye color The parents were vestigial, red eyed color female and normal wing size, sepia eyed color male Diagram of P1 cross: You are crossing F1s.
