900 bacteria had two recessive alleles out of a total of every 10,000 bacteria. Using the Hardy-Weinberg equation(s), determine the frequency of the recessive and dominant alleles.

Below is the mapping data from three different crosses of Hfr strains with separate samples of an F- strain. Appearance of Genes in F- cells Hfrl: Genes d+ c+ ft et g+ Time (min) 4 15 26 44 58 Hfr2: Genes b+ d+ c+ f+ g+ 59 Time (min) 3 5 16 27 Hfr3: Genes et f+ c+ d+ b+ Time (min) 6 24 35 46 48 Use the mapping data from these interrupted conjugation crosses to construct a genetic map for these genes, indicating their order on the bacterial chromosome and the distances between them.

Given an observed F2 data set, a specified gene, and two phenotype classes (disease and wild type), the number of degrees of freedom for the chi-square goodness of fit test when studying the F2 generation is: A)-1. B)0. C)2. D)1. E)3.

You would like to isolate loci in the genome that influence plant height in tomato plants. Describe how you would achieve this through QTL mapping. Choose a true breeding tall strain and a true breeding short strain and compare the genomic sequences. Choose a true breeding tall strain and true breeding short strain and type them for molecular markers. Mate them together to produce F1 offspring and evaluate whether the F1 are tall or short. Choose two true breeding tall strains and compare the genomic sequences. Choose a true breeding tall strain and true breeding short strain and type them for molecular markers. Mate them together to produce F1 offspring. Genotype the F1 to identify makers that are associated with differences in plant height. Choose a true breeding tall strain and true breeding short strain and type them for molecular markers. Mate them together to produce F1 offspring, then backeross the F1 offspring to produce F2 offspring carrying recombinant chromosomes from tall…
