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 is the recombination frequency for the traits of leg color and mandible length? O 1% O 99% O 48% O 52%

The gel image below shows 7 alleles, let’s call them 1-7 in order of size, with 1 being the largest and 7 being the smallest. In this sample of 11 individuals, how many times does allele 3 appear? Please type your answer as a number, not a word. ANSWER: In the image below allele 3 appears ? times.
You perform a cross between two plants, one MmPp and one mmpp, and obtain offspring with the following phenotypes: 42 MP; 374 Mp; 367 mP; 27 mp. What can you conclude from these data? Group of answer choices The M and P genes are on different chromosomes The recombinant progeny are mP and Mp The M and P genes are far apart on the same chromosome The recombinant progeny are MP and mp
The gel image below shows 7 alleles, let’s call them 1-7 in order of size, with 1 being the largest and 7 being the smallest. In this sample of 11 individuals, how many times does allele 5 appear?
What would be the gene map for the following genes with known recombination frequencies? D and A is 5.1 cM, A and C is 15.8 cM, A and B is 7.8 cM, C and D is 10.7 cM, and C and B is 8.0 cM.
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?
You perform a cross between two plants, one MmPp and one mmpp, and obtain offspring with the following phenotypes: 42 MP; 374 Mp; 367 mP; 27 mp. What can you conclude from these data? ONLY PICK ONE OF THE ANSWERS: The M and P genes are on different chromosomes The recombinant progeny are mP and Mp The M and P genes are far apart on the same chromosome The recombinant progeny are MP and mp
What does it mean when an individual is found to be “homozygous” at a DNA profiling locus? They have three alleles at the locus They got different alleles from their mother and father They got the same alleles from their mother and father Their children got two alleles from them Their children got no alleles from them
In pre-DNA fingerprint days, blood type was often used in paternity disputes to exclude possible fathers. If the man in question has type B blood, and the child has type A blood, and the mother has type AB blood, can the man be the father of the child? Group of answer choices Yes, but only if he is homozygous for the B allele No Yes, but only if he is heterozygous for the B allele Yes, but only if both of his parents were Type AB
A geneticist identifies 117 recombinant offspring out of a total of 1,359. What is the recombination frequency?
How to build a genetic map? What is necessary? How does it relate to the physical distance? i. If I have 3 genes and want to learn their distance in cM, how many types of crosses do I need? Why?
The table below shows the progeny of a test cross of a heterozygote (JjBbRr). Each row shows the number of progeny that inherited each combination of alleles from the heterozygous parent. You've already determined the gene order (B is in the middle) and labeled each type of progeny. Using this information, what is the recombination frequency between J and B? Alleles: Type: Count: J B R Parental 132 j b r Parental 135 J b R DCO 15 j B r DCO 11 J b r SCO (J-B) 59 j B R SCO (J-B) 55 J B r SCO (B-R) 38 j b R SCO (B-R) 40 Group of answer choices 0.214 0.235 0.289 the correct answer is not available. 0.503 0.14
