On one chromosome, 13) alleles C and D are found, while the homologue contains alleles c and d. Which of the following would be evidence of a recombination event? A) Alleles C and D together on one chromosome B) Alleles c and d together on one chromosome Q Both alleles C and d together on one chromosome and alleles c and D together on one chromosome D) Alleles c and D together on one chromosome E) Alleles C and d together on one chromosome 14) Which of the following are highly desirable characteristics of an organism that make it 1) relatively easy to construct a genetic linkage map? A) Easily crossed C) Produces large numbers of offspring B) Short generation times D)All of the answers are correct 15) while mapping two genes in Drosophila, you observe 30 recombinants among 200 total ?? - offspring. What is the distance between these genes? A) 200 map units C) 6.67 map units B) 15 map units D) 30 map units 16) A map distance of 23.6 between two genes indicates which of the following? 16) A) There are 23.6 other genes between the two genes of interest B) 23.6% of the offspring do not survive C) 23.6% of the offspring exhibit recombination between the two genes D) The genes are 23.6 millimeters apartExplanation / Answer
