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?...

Three genes with recessive mutant phenotypes are located on the same chromosome in maize: waxy endosperm (wx), shrunken endosperm (sh), and virescent seedling (v). A plant with all three mutant phenotypes is crossed with a true-breeding, wild-type plant. Resulting F1 plants are then backcrossed to the parental mutant line to produce the following progeny: Waxy Shrunken Virescent Number wx sh + 89 + + v 92 + + + 1482 wx sh v 1475 + sh + 480 wx +...

Question #1: Thomas Hunt Morgan used genetic mapping to map out genes on the chromosomes. He found that alleles that are not genetically linked, can still be on the same chromosome. Alleles A and Z are not genetically linked (recombination frequency is 50%) If the recombination frequency between different alleles are: AZ: 50% G-Z: 50% A-G: 8% T-D: 24% G-T: 39% TZ: 50% A-T: 47% DZ: 25% A. Are A and Z on the same chromosome? Why or why not?...

Three genes with recessive mutant phenotypes are located on the same chromosome in maize: short stem (ss), defective endosperm (de), and virescent seedling (v). A plant with all three mutant phenotypes is crossed with a true-breeding, wild-type plant. Resulting F1 plants are then backcrossed to the parental mutant line to produce the following progeny: Waxy Shrunken Virescent Number ss + + 290 + de v 282 ss de + 89 + ...

43. Genes a and b are X-linked and are located 7 mu apart on the X chromosome of Drosophila. A female of genotype a+ b/a b+ is mated with a wild-type (a+b+/Y). a. What is the probability that one of her sons will be either a+b+ or a b+ in phenotype? b. What is the probability that one of her daughters will be a+b+ in phenotype? 44. Three recessive autosomal mutations in Drosophila: a versus wild-type A. b versus B,...

Three genes are located on the same chromosome and are known to be 8 mu apart between A and B, and 12 mu apart between B and C. The heterozygous AaBbCc genotype individuals were crossed to homozygous recessive aabbcc genotype individuals (test cross) and observed 3 double crossover offsprings. If this cross produces a total of 500 offsprings, what are the expected numbers of double crossover offsprings and calculate the Interference (1) value. (3 points) 4·

Genetic Linkage The six genes listed below are all located on Chromosome 2 of Drosophila melanogaster. Your goal is to construct a genetic map of Chromosome 2. That is, determine the order of these genes along chromosome 2 and the map distance in centimorgans between each gene. To complete this task, you will be given the results of a variety of two-point test crosses involving these genes. For each test cross you may assume that the female is heterozygous and...
