Starting with the highest recombination rates, arrange the genes as below :
R --------------------- 35 % ----------------L2
W2-------18%-------L2
R-------17%-----------W2
So order of the gene is : R W2 L2
Recombination rates between three loci in corn are shown here, R and W2 17% R and...
Recombination rates between three loci, L2, R, and W2, in corn are shown in the table. Loci L2 and R R and W2 L2 and W2 Recombination rate 35% 17% 18% Use the recombination rates to arrange the three genes on the section of DNA. DNA strand Answer Bank R W2 L2
Chromosome 3 of corn carries three loci (b for plant color booster, v for virescent, and lg for liguleless). A test-cross of triple recessives with F1 plants heterozygous for the three genes yields progeny having the following genotypes: + v lg 325 b + + 275 b + lg 128 + v + 112 + + lg 74 b v + 66 + + + 22 b v lg 18 Total 1010 What the distance between virescent and liguleless?
1. A,B and C are linked genes. Recombination between A and B is 10%; between A and C IS 7%; AND BETWEEN B AND C IS 17%. What is the order of these genes on chromosome?
P, D, and Q are three genes found on a single chromosome in greyhounds. The recombination frequencies between the three genes are shown below. In which order are these genes found on the greyhound chromosome?P-D = 50%;P-Q=20%;D-Q = 30% OP-Q-D OP-D-Q OD-P-Q
Mapping genes with recombination frequencies in Drosopna 1. Suppose you know of three linked loci on the Drosophila X chromosome (a, b, and c). Assume that you are starting out with true-breeding stocks that show all three recessive traits and true-breeding stocks that show all three dominant traits. A. If you wanted to do a 3-point test cross to map the three loci, how would you set up the cross? What genotypes do you use for males and females in...

The genetic map between four loci is given: P—2cM—Q-1cM-R---6cM---S The probability of recombination between P and S is Select one: a. 0.009 b. 0.012 c. 0.00012 d. 0.09 e. 0.9
2. Genes A and B are linked on the same chromosome. The recombination frequency between the two genes is r = 0.2. Given this cross between two individuals: AB/ab x aB/Ab, what is the probability of the cross giving progeny of the genotype ab/ab?
4. You are studying three genes in corn and performed a three-point cross. The three genes are green (V) vs Viniscent (V) seedlings, blue (Pr) vs red kernels (pr) and white (B ) or brown (bm) leaf midrib color. The table below list the offspring resulting from a testcross with a female F1 heterozygote. Type of gamete (NR, SCO, DCO Phenotype Progeny Gamete from F1 heterozygote Virescent seedling red 101 kernel Red kernel 175 Red kernel, brown midrib 259 Virescent...
(9 points) You are interested in studying recombination frequencies in wasps. You identify a queen that is heterozygous at three different loci on chromosome 5: G, H, and R. As queen wasps can produce haploid male offspring without fertilizing their eggs, you decide to look only at the genotypes of her male offspring in your analysis. Below is a list of the genotypes of her male offspring, and the number of individuals that fall into each genotypic class. 92 168...
