Homework Answers
Answer1a): a. A and B
Answer1b): b. A and C
Comments: Recombination frequency is likely a reflection of the physical distance between two genes. Recombination takes place between the incompletely linked genes (not among the completely linked genes). The recombination frequency is directly proportional to the distance among the genes (that is recombination frequency is more in two distinctly located genes than the two closely located genes). More likely the closer genes are inherited together (Co-occurrence). In the above question gene A and B are closely located so the recombination frequency if lowest. However, gene A and gene C are distinctly located so the recombination frequency is more among gene A and gene C.

You believe that there has been a reciprocal translocation between genes A and B in a species of plant that you are studying. The genes are known to be on different chromosomes in a closely related species. Which of the data below would support that a reciprocal translocation had happened? A. The recombination frequency decreases B. The two genes show a recombination frequency of 50% C. The two genes show linkage D. The recombination frequency of linked genes drops to...

In Drosophila, the genes for black (b) body and curved (c) wings are linked on the same chromosome. The frequency of recombination between b---c is 0.276. How many recombinant offspring would be expected if 2000 progeny were produced from a testcross between a female heterozygous for both genes and a homozygous recessive male?

genes A,B,C are linked in order. frequency of single crissover between A-B =15% and between B-C = 20%. coeficient of coincidence= .7 how would you calculate ans how many double crosses will actually show up when a triple heterozygote is test corssed?

Genes A and B are linked, with 20 percent recombination. What would be the phenotypes, and the probability of each, among progeny of the following cross? A B/abxa b/ab Parentals are Aband a B and you expect 45% of each, recombinants are AB and a b with 5% of each Parentals are AB and a b and you expect 45% of each, recombinants are Ab and a B with 5% of each Parentals are A B and a b and...

2. In Drosophila, the genes b (black body), vg (vestigial wings), and c (curved wings) are linked. The genes are in the order vg-b-c. Shown here is the genotypic arrangement in a heterozygous fly: vg- b+c+ ===== vg+ b c- a. Indicate all of the different gamete genotypes that could arise from this parent. b. What two gamete genotypes will be made in the highest frequency from this heterozygote? c. What two gamete genotypes will be made in the lowest...

You are studying 3 genes X,Y and Z that are linked (and in that order; Y is in the middle). The distance between X and Y is 10 map units and the distance between Y and Z is 8 map units. If your test cross resulted in 1500 progeny and you observed 5 double crossovers would you conclude that interference has occurred? If yes, how much interference has occurred?

Genes A and B are linked. Individual plants homozygous for different combinations of these genes (AABB, aabb, AAbb, aaBB) were crossed at random to produce F1 plants. The F1 plants were self pollinated to produce the F2. The F2 progeny from six of the F1 self pollinations are listed below. Number of F2 plants in each phenotypic class F1 Plant-------------------AB--------------- Ab --------------- aB----------------- ab 1 --------------------------0 ----------------98 ---------------- 0------------------ 32 2 ------------------------- 64 --------------10 -----------------8...
