Question: A bacterium with genotype A+B-C-was transduced by a particle carrying the linked genes A-B+C+, and A+B+C+ recombinants were selected. The reciprocal cross was also performed. The number of A+B+C+ recombinants was the same in both the first cross and the reciprocal cross. What information does this give you about the order of the three genes? (please explain in as much details)- these genes are assumed as any random genes

    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?

    You are following the inheritance of three genes: A, B and C. A and B are on the same chromosome; C is on a different chromosome from A and B (for example; A and B are on chromosome 1 and C is on chromosome 4).Which option correctly represents the genotype of an individual who is heterozygous for all three genes?What is the recombination frequency for unlinked genes (i.e., genes that sort independently)? Frequency is given as a number from 0...

    Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...

    For Drosophila, let’s consider three genes a, b, and c. We know where a and b are located, and have a nice idea about c. You conduct a three-point cross to figure it out for sure. We’ll use a, b, & c to refer to the three mutants, and + to refer to the wild-types. Here are the progeny counts from a heterozygote by homozygous mutant wild-type: a, b, c: 770 +, +, +: 384 a, +, +: 80 +,...

    Mapping genes with recombination frequencies in Drosophila 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...
