Textbook Question
Chapter 3, Problem 29P
A wild-type Drosophila male and female are crossed, producing 324 female progeny and 161 male progeny. All their progeny are wild type.
a. Propose a genetic hypothesis to explain these data.
b. Design an experiment that will test your hypothesis, using the wild-type progeny identified above. Describe the results you expect if your hypothesis is true.

The fruit fly, Drosophila melanogaster, a vestigial female fly is mated to a male that is scarlet eyes and bristled. Phenotypically wild type F1 female progeny were mated to fully homozygous (mutant) males, and the following progeny (of 1000 total) were observed (shown on table)
a. Which gene is in the middle?
b. What are the map distances between the three genes for this question?
c. Calculate and show the work for coefficient of coincidence
d. Calculate the interference. What does this mean and what does it tell you?
Two normal looking fruit flies were crossed and in their progeny, there were 202 females and 98 males. What is unusual about this result? provide a genetic explanation for this anomaly and provide a test of your hypothesis
The wild-type (normal) fruit fly, Drosophila melanogaster, has straight wings and long bristles. Mutant strains have been isolated that have either curled wings or short bristles. The genes representing these two mutant traits are located on separate chromosomes. Carefully examine the data from the following five crosses shown below (running across both columns).
(a) Identify each mutation as either dominant or recessive. In each case, indicate which crosses support your answer.
(b) Assign gene symbols and, for each cross, determine the genotypes of the parents.

- Write your own two-factor genetic linkage problem. Then, solve the question to create a linkage map for your example question, showing the relative positions of the genes and the map distance between the genes.arrow_forwardYou believe that the gene you're investigating, eyes absent, is an autosomal recessive mutant allele F7 ge in Drosophila. You set up a cross between a true-breeding mutant male and a true-breeding wildtype female to obtain the F1 generation. You then cross the F1 flies. In the F2 offspring, you observe the following: 237 wild-type males 180 wild-type females 70 mutant males 83 mutant females Based on these findings, is the mutant allele autosomal recessive? How do you know?arrow_forwardA couple who are both heterozygous for an autosomal recessive mutation that is narrowly expressed and fully penetrant are planning on having three children.

- You have determined that the gene order for three linked genes being studied is A B C. The number of recombinants resulting from crossover between genes A and BC are 44 and 48, respectively, while the double-crossover progeny total 4 and 6. What is the recombination frequency between genes A and B if the total progeny from the cross is 1000? Show all of your work.arrow_forwardSuppose that you are tending a mouse colony at a genetic research institute, and one day you discover a mouse with twisted ears. You breed this mouse with twisted ears and find that the trait is inherited. Both male and female mice may have twisted ears, but when you cross a twisted-eared male with a normal-eared female, you obtain results that differ from those obtained when you cross a twisted-eared female with a normal-eared male: the reciprocal crosses give different results. Describe how you would determine whether this trait results from a sexlinked gene, a sex-influenced gene, genetic maternal effect, a cytoplasmically inherited gene, or genomic imprinting. What crosses would you conduct, and what results would be expected with these different types of inheritance?arrow_forwardWhat is probability, and how is it applied in genetic analysis?arrow_forward
