DATA 29. MA R. W. Allard and W. M. Clement determined recombination rates for a ANALYSIS series of genes in lima beans (R. W. Allard and W. M. Clement. 1959. Journal of Heredity 50:63–67). The following table lists paired recombination frequencies for eight of the loci (D, Wl, R, S, L, Ms, C, and G) that they mapped. On the basis of these data, draw a series of genetic maps for the different linkage groups of the genes, indicating the distances between the genes. Keep in mind that these frequencies are estimates of the true recombination frequencies and that some error is associated with each estimate. An asterisk beside a recombination frequency indicates that the recombination frequency is significantly different from 50%. Recombination frequencies (%) among seven loci in lima beans WI S Ms G 2.1* 39.3* 52.4 48.1 53.1 51.4 49.8 WI 38.0* 47.3 47.7 48.8 50.3 50.4 51.9 52.7 54.6 49.3 52.6 26.9* 54.9 52.0 48.0 48.2 45.3 50.4 Ms 14.7* 43.1 C 52.0 * Significantly different from 50%.

Determine the gene order (which gene is in the middle?), as you were shown in exercises for Tutorial 6, showing all your work. Construct a genetic map for the three genes, including the map distances between them. Clearly indicate the logic you followed and show all your calculations. Include the full distance calculations for the two most distanced genes (do not just add the other 2 distances).

17. Please solve and make sure all relevant calculations of m.u. take into consideration double crossovers!

In a three-point linkage analysis, the RF (Recombinant Frequency) for three genes were determined as the following: genes A and B (RF=15%), genes B and C (RF=22%), genes A and C (RF=35%). Based on this analysis, which one of three genes is located in the middle? O gene B Ogene A O gene C O cannot be determined

What is the probability this parent will produce a gamete with the dominant allele? b. What is the probability this parent will produce a gamete with the recessive allele? C. If 31 sperm cells are collected from this guinea pig, how many would you expect to have the recessive allele (as determined by sequencing the gene)? !!!

Problem 1: 11.2 10.9 garnet eyes M A new gene is being investigated in fruit flies. The recessive allele of this gene (t) causes the flies' feet to grow tiny tapdance shoes, while the dominant allele (t*) permits wild-type feet to develop. Preliminary studies indicate that this new gene is located on the X-chromosome. You decided to perform a two-point testcross to determine its position relative to the well-established crossveinless wings gene (cv). You cross a female heterozygous for both genes with a testcross male fly and obtain the male offspring results shown in table 1, below. Using this information, answer the following questions: # male offspring 13 405 401 11 forked bristles a) is the original…
