You are working with a new species of spider in the lab. Wild type spiders have black legs and long mandibles. Mutants have black/brown striped legs and short mandibles. You perform a cross between wild type and mutant spiders. Your results : 5,502 wild type; 5,877 mutant; 69 black/brown striped, long mandibles; 52 black, short mandibles. What information does the recombination frequency tell you about the traits? (You will need to solve the RF first if you haven't done so in the other problem.) * A. Crossing over occurs frequently between the two traits. B. They are unlinked genes. C. They are located on separate chromosomes D. They are located very close together on the same chromosome.

A geneticist identifies 117 recombinant offspring out of a total of 1,359. What is the recombination frequency?
When you testcross the offspring of ccWW x CCww, you get the following results: CcWw = 135 Ccww = 430 ccWw = 390 ccww = 120 What is the frequency of recombination? (You must show and clearly label ALL work please)
Figure 13.4 Which of the following statements is true? Recombination of the body color and red/ cinnabar eye alleles will occur more frequently than recombination of the alleles for wing length and aristae length. Recombination of the body color and aristae length alleles will occur more frequently than recombination of red/brown eye alleles and the aristae length alleles. Recombination of the gray/black body color and long/short aristae alleles will not occur. Recombination of the red/brown eye and long/short aristae alleles will occur more frequently than recombination of the alleles for wing length and body color.
Hemophilia and color blindness are both recessive conditions caused by genes on the X chromosome. To calculate the recombination frequency between the two genes, you draw a large number of pedigrees that include grandfathers with both hemophilia and color blindness, their daughters (who presumably have one chromosome with two normal alleles and one chromosome with two mutant alleles), and the daughters sons. Analyzing all the pedigrees together shows that 25 grandsons have both color blindness and hemophilia, 24 have neither of the traits, 1 has color blindness only, and 1 has hemophilia only. How many centimorgans (map units) separate the hemophilia locus from the locus for color blindness?
If two genes are unlinked the recombination frequency will be? 25% 50% 75% 100%
In a cross between mice the genotypes AB/ab x ab/ab, what is the recombination frequency if the progeny numbers are 72 AB/ab, 68 ab/ab, 17 Ab/ab, and 21 aB/ab? The alleles are shown for each chromosome, separated by a slash (/)
In a diploid plant species, an F1 with the genotype Mm Rr Ss is test crossed to a pure breeding recessive plant with the genotype mm rr ss. The offspring genotypes are as follows: Genotype Number Mm Rr Ss 687 Mm Rr ss 5 Mm rr Ss 68 Mm rr ss 196 mm Rr Ss 185 mm Rr ss 72 mm rr Ss 8 mm rr ss 679 Total 1900 1. Why is the recombination frequency for the outside pair of genes not equal to the sum of the recombination between the adjacent gene pairs?
Calculate the recombination frequency from the following data collected from a breeding experiment with butterflies. Parent 1: dihybrid, long legs and blue wings. Parent 2: double recessive, short legs and white wings Offspring: 50 long legs and white wings 200 long legs and blue wings 50 short legs and blue wings 200 short legs and white wings Recombination frequency is: Select one: a. 0.25 (25%) b. 0.10 (10%) c. 0.20 (20%) d. 0.33 (33%) e. 0.50 (50%)
