Chapter 3, Problem 3P
In a test of his chromosome theory of heredity, Morgan crossed an F1 female Drosophila with red eyes to a male with white eyes. The F1 females were produced from Cross A shown in Figure 3.19. Predict the offspring Morgan would have expected under his hypothesis that the gene for eye color is on the X chromosome in fruit flies.

Q. Construct a linkage map showing the correct order of these genes and estimate the distances between them.
In DrosophilaI, yellow body (y), crossveinless (cv), and forked bristles (f) are all found in the X chromosome, in that order. Yellow is 14 map units from crossveinless, and crossveinlessis 32 map units from forked. A yellow, forked female is crossed to a crossveinless male. An F1 female is crossed to a yelow, crossveinless, forked male, yielding the F2 generation. In the F2, what is the probability of obtaining progeny that express crossveinless and forked, but not yellow? Assume a coefficient of coincidence of 1.
In the F2, what is the probability of obtaining progeny that are completely wild type?
In the F2, what is the probability of obtaining progeny that express crossveinless, but not yellow or forked?
In Drosophila,, the curled mutation (cu, chromosome 3, position 50.0) results in wings that curl up,
while ebony (e, chromosome 3, position 70.7) results in a dark body. True breeding, wild type females
are mated with true breeding males with curled wings and ebony bodies.

- In Drosophila, red eyes is the wild-type phenotype. There are several different genes that affect eye colour. One allele causes purple eyes, and a different allele causes sepia eyes. When flies with purple eyes were crossed with flies with sepia eyes, all of the F1 offspring had red eyes. The F1 offspring were allowed to mate with each other and the following data were obtained: 146 purple eyes201 sepia eyes444 red eyes Formulate a hypothesis that you think is consistent with the observed data. Test the goodness of fit between the data and your hypothesis.arrow_forwardYou have been given a virgin Drosophila female. You notice that the bristles on her thorax are much shorter than normal. You mate her with a normal male (with long bristles) and obtain the following F1 progeny1 3 short-bristled females, 1 3 long-bristled females, and 1 3 long-bristled males. A cross of the F1 long-bristled females with their brothers gives only long-bristled F2. A cross of short-bristled females with their brothers gives 1 3 short-bristled females, 1 3 long-bristled females, and 1 3 long-bristled males. Provide a genetic hypothesis to account for all these results, showing genotypes in every cross.arrow_forwardA mutation of Drosophila has a wing condition known as beaded. When a beaded fly was crossed with a pure-line normal fly, 53 beaded and 47 normal F1 's were produced. When two of the F, beaded flies were mated, 67 beaded and 33 normal F2's were produced. Explain the genetics of the beaded trait and give the genotypes of all P and F1 generation flies.arrow_forward
- Imagine Drosophila genes C, D, and E are autosomal genes located close to each other on the same chromosome (same assumptions as the first problem). You cross a C D E homozygote with a c d e homozygote, then cross the F1 females with a c d e homozygous male. Of 400 progeny, you observe the following phenotypes: 135 CDE 139 cde 22 cDE 18 Cde 42 CdE 38 cDe 3 cdE 3 CDe a. What is the order of the genes?

- The orange coat color allele in cats is located on the X chromosome and is one of two genes responsible for tortoiseshell coat color. Two true-breeding cats are crossed, a black male and an orange female. Considering the female kittens, how many X chromosomes would be silenced at the indicated developmental stages: primary oocyte, single-cell female embryo, and adult female somatic cell. Considering the female kittens, some interesting coat colors were found. The kitten named Elsa had one black patch and one orange patch. The kitten named Annika had ten black patches and ten orange patches. Explain why these sisters look different based on their development from a single-cell female embryo to the somatic cells of the kitten.arrow_forwardImagine a germ cell for an animal that is 2n=4. Gene A and B are found on chromosome one, and the cell is homozygous for A(AA) and heterozygous for Bb. Gene D is found on chromosome 2 and the germ cell is heterozygous for the Allee of the gene (Dd). Meiosis for this germ cell results in the following four gametes, and one crossing over event during meiosis ABD, ABd, AbD, Abd. Draw the chromosomes in cell during metaphase of meiosis 1. Make sure to include chromosomes, the allele in the correct locations on the chromosomes AFTER the crossing over event, and spindle fibers.arrow_forwardA female Drosophila with the mutant phenotype 'notched wings' was mated to a wild type male. Two-thirds of the progeny were female. Half of the females had notched wings and the other half had wild type wings and all the male progeny had wild type wings. When the notched progeny were mated to their wild type brothers, the same results were obtained. Explain.arrow_forward
