In a three-point linkage analysis, the RF values for three genes were determined as the following: genes A and B (RF=25%), genes B and C (RF=50%), genes A and C(RF=35%). Based on this analysis, which of the following statement is correct? Gene B is only linked to gene A but not to gene C, because the RF value of gene B and C is 50%. O Of the genes that are linked, A and C is the furthest apart with a distance of ~35 cM. O Of the three genes, B and C is the furthest apart with a distance of 50 cM. O Of the three genes, B and C is the furthest apart with a distance of ~60 cM.

Why does linkage disequilibrium represent an advantage and a disadvantage for mapping genetic variants associated with complex traits?

Identity gene 1 (bl, pr, vg) Identity gene 2 ( bl, pr, vg) Identity gene 3 ( bl,pr, vg) How many map units separate genes 1 and 2 ( Distance 1)? How many map units separate genes 2 and 3 ( distances 2) ?

Based on the information provided, you can infer that individual III-1 inherited both the      A.)  and the      B.)  of the SNP from his father.   Pick Correct Answer A.) allele that causes neucrofibromatosis or wild type allele B.) G or T

Given the experimental set up below, and knowing the genes for stalked eyes (st) and black bodies (b) are on the same chromosome and recessive to wild type (un-stalked eyes and light body).  F2= a=489, b=56, c=497, d=49 A)  How many recombinant animals are in the F2 generation? B) ( How far apart, (as both a % recombination and in map units) are the stalk eyed and black bodied genes on this chromosome?

Would you be able to draw a circular map of the seven genes? I have trouble with correct position of the genes

QTL mapping and GWA (association) mapping are two different methods used to identify genes that affect complex traits. For each of the following statements, choosewhether it applies to QTL mapping, association mapping, or both.whether it applies to QTL mapping, association mapping, or both.

A research team interested in mapping human genes discovered a new restriction length polymorphism (RFLP). The nature of the polymorphism is shown in the figure below.  a) They test the RFLP in a family with the pedigree below. The individuals colored blue are affected by hemophilia, a blood-clotting disease. On what chromosome is the RFLP found?

A pair of paralogous repeats, A and B, have 96% sequence similarity and therefore can promote non-allelic homologous recombination (NAHR). They exist in four possible arrangements in a genome, illustrated below as arrangements 1 – 4. What is the result of NAHR between repeats A and B in arrangement 1? A.Translocation between chromosomes 1 and 2 resulting in monocentric chromosomes B.Deletion or duplication of the region between A and B C.Translocation between chromosomes 1 and 2 resulting in acentric and dicentric chromosomes D.Inversion of the region between A and B
