Please explain how I can solve this. Thank you You wanted to draw a linkage map for three genes in the fruit fly (A, B, C) that you suspect are linked. You have done a three-point testcross and found that out of the 1500 progeny in the cross, 612 are a · b · c, 603 are A · B · C, 93 are a · B · C, 85 are A · b · c, 53 are a · b · C, 47 are A · B · c, 5 are A · b · C, and 2 are a · B · c. From this data, you can deduce that the genes are linked and the distance

Can you please help me solve and explain this question: Consider two genes A and B. If there are on average 8.5 crossovers taking place between A and B. what is the map distance between A and B? (map units)
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.
In letter B: If the map distance equals the number of recombinant/total of offspring, wouldn't it be 24/806 x 100? Wouldn't we add both recombinants? Can you explain letter C? I don't grasp that concept well. And since I'm using my question already, would you be able to answer D. Thank you!
I am trying to understand how linkage works, and I am hoping someone can explain how to solve the following problem: The diagram shows the linkage maps for four genes: A, B, C, and D. Which genes are most likely to undergo recombination? Which genes are least likely to recombine? A.) A and D B.) C and D C.) B and C
Part A: If the two genes are 30 mu apart and the plant is (AB/ab), what proportion of gametes from a single plant will be AB? Enter your answer as a decimal to three places (for example: 0.120). Part B: If the two genes are 30 mu apart and the plant is (AB/ab), what proportion of gametes from a single plant will be Ab?

Three autosomal recessive mutations in yeast, all producing the same phenotype (m1, m2, and m3), are subjected to complementation analysis. Of the results shown below, which, if any, are alleles of one another? Predict the results of the cross that is not shown—that is, m2 * m3. Cross 1: m1 * m24 F1: all wild-type progeny Cross 2: m1 * m34 F1: all mutant progeny

You are conducting independent research for your Honors Thesis in a Drosophila research lab. One of the graduate student researchers has provided you with two mutant strains of Drosophila. One has scarlet eyes, and the other has brown eyes. You cross homozygous scarlet-eyed male Drosophila with female flies homozygous for the brown-eye color allele, and all of the male and female F1 flies have wild-type eyes. Crosses involving F1 males x F1 females yield the results shown below. You know the traits involved are autosomal, and that reciprocal parental crosses produce similar results. A) Please define the alleles represented in this cross. B) List the genotypes of all classes of individuals in the P, F1, and F2Be sure to use the alleles you defined in Part A Parental (P) Generation Genotype of Homozygous scarlet-eyed males: Genotype of Homozygous brown-eyed females: F1 Generation: Genotype of Wild-type (red-eyed) males and females: F2 Generation: Genotype of wild-type males and…
