A geneticist determines that the order of four genes on a specific chromosome is CABD because the recombination frequencies were 35% for C-D, 24% for A-D, 23% for B-D, and 10% for A-B. What has the geneticist constructed?
The following recombination frequencies are calculated for four linked genes in the image attached: What is the frequency of crossing-over between A and D? a. 8% b. 6% c. 15% d. 11%
You breed two monster parents (green, hairless) GGhh and ggHH (white, hairy) to produce F1 offspring (green, hairy). Genes G and H are on the same chromosome. a. What are the dominant phenotypes? b. What are ALL of the potential gamete genotypes that could be created by an F1? Clearly indicate the recombinant genotypes. c. Explain how recombinants are created. d. What are the potential offspring genotypes from the cross of a F1 monster with a homozygous recessive monster. e. From this test cross you get 152 green, hairless; 23 green, hairy; 148 white, hairy, and 27 white, hairless. Calculate the chi squared to test the independent assortment hypothesis and determine if these genes assort independently.

Consider the genetic map below. (a) In a total of 1000 observed progeny, how many would be expected to be parental, non-recombinant? (b) If the total number of observed double-crossover recombinant progeny is 0, what is the interference? Show step by step work for full credit. A-------10cm-----B—2.5cm----C
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.
Recombination frequencies have been determined between four genes (A, B, C and D) as follows: A-B: 20%, B-C: 50%, A-D: 50%, C-D: 5% Which of the four genes is/are likely linked on the same chromosome?

I am studying a pair of genes, A and B, that I think are both located on the same chromosome. After counting offspring from a test cross of an AaBb individual, I notice that recombination frequency for genes A and B is very low (~4%). From this, I can conclude that Select one: a. A and B are sex-linked b. A and B are actually on different chromosomes c. A and B are very close together on the same chromosome d. A and B on the same chromosome, but far apart

Figure 13.4 Which of the following statements is true? Recombination of the body color and red/ cinnabar eye alleles will occur more frequently than recombination of the alleles for wing length and aristae length. Recombination of the body color and aristae length alleles will occur more frequently than recombination of red/brown eye alleles and the aristae length alleles. Recombination of the gray/black body color and long/short aristae alleles will not occur. Recombination of the red/brown eye and long/short aristae alleles will occur more frequently than recombination of the alleles for wing length and body color.
