Chapter 5, Problem 27P

In tomatoes, the allele T for tall plant height is dominantto dwarf allele t , the P allele for smooth skin is dominant to the p allele for peach fuzz skin, and the allele R for round

fruit is dominant to the recessive r allele for oblong fruit. The genes controlling these traits are linked on chromosome 1 in the tomato genome, and the genes are arrangedin the order and with the recombination frequenciesshown.

Chapter 5, Problem 27P, 5.27 In tomatoes, the allele for tall plant height is dominant to dwarf allele, the allele for

A pure-breeding tall, peach fuzz, round plant is crossedto a pure-breeding plant that is dwarf, smooth, oblong. What are the gamete genotypes produced by each ofthese plants?

What are the genotype and phenotype of the F1 progeny of this cross?

What are the genotypes of gametes produced by the F1 , and what is the predicted frequency of eachgamete?

The F1 are test-crossed to dwarf, peach fuzz, oblong plants, and 1000 test-cross progeny areproduced. What are the phenotypes of test-cross progeny, and what number of progeny is expected ineach class?

In a cross in Drosophila, a female heterozygous for the autosomallylinked genes a, b, c, d, and e (abcde/ + + + + +) was testcrossedwith a male homozygous for all recessive alleles (abcde/abcde).Even though the distance between each of the loci was at least3 map units, only four phenotypes were recovered, yielding thefollowing data:   Phenotype                   No. of Flies+ + + + +                      440a b c d e                         460+ + + + e                         48a b c d +                           52                         Total = 1000 Why are many expected crossover phenotypes missing? Can anyof these loci be mapped from the data given here? If so, determinemap distances.
You are studying four linked genes located on chromosome 2 in the fruit fly Drosophila melanogaster: adp (which contributes to obesity), b (which contributes to body color), pr (which contributes to metabolism), and vg (which contributes to wing formation). A series of crosses between pair-wise combinations of these mutations yielded the following recombination frequencies between the indicated loci: pr and adp 9% adp and b 6% pr and b 3% vg and b 10% vg and pr 7% What is the genetic distance in map units (cM) between the adp and vg loci? 16 9 6 4
Semi-sterility in corn, as seen by unfilled ears with gaps due to abortion of approximately half the ovules, is an indication that the strain is a translocation heterozygote. The chromosomes involved in the translocation can be identified by crossing the translocation heterozygote to a strain homozygous recessive for a gene on the chromosome being tested. The ratio of phenotypic classes produced from crossing semi-sterile F1 progeny back to a homozygous recessive plant indicates whether the gene is on one of chromosomes involved in the translocation. For example, a semi-sterile strain could be crossed to a strain homozygous for the yg mutation on chromosome 9. (The mutant has yellow-green leaves instead of the wild-type green leaves.) The semi-sterile F1 progeny would then be backcrossed to the homozygous yg mutant. (a) What types of progeny (fertile or semi-sterile, green or yellow-green) would you predict from the backcross of the F1 to the homozygous yg mutant if the gene was not on…
