45 c. Following progeny recovered from standard test cross design using the plexus locus and the vermillion locus (v, vermillion eyes) and the following progeny are recovered:
v px / v px 235
v + / v px 241
+ +/ v px 255
+ px/ v px 259
Describe the linkage map between curved, plexus, and vermillion. (4 marks)

9. You have been asked to determine the map distances between two SNP loci R and Q in wheat. The following cross was undertaken: RARG QcQrx RARA QcQc and yielded progeny as shown below. RARA QrQc RARA QcQc 259 235 242 264 What are the genotypes of the parents of this cross? a) Give the map distance in centiMorgans between these two loci. (Show your work) c) Can you reject hypothesis of no linkage using a Chi-square test? (Show your...
What are the genotypes of the parents in a standard dihyrbid test cross? For example, if a standard test cross is conducted for the linked genes for curved (c, curved wings) and plexus (px, extra wing veins) wings in Drosophila produces a progeny with the following phenotypes: c px / c px 80 c + / c px 400 + +/ c px 90 + px/ c px 430 I am aware that the genotypes with the highest frequency are...
1. The following diagram shows the genetic map for a chromosome. A B C D 10cM 5cM 40cM If a diploid female heterozygous for A and D (A D//a d) is testcrossed to a homozygous recessive male (a d/a d), what percent of the progeny are predicted to have the genotype A d/a d? A. 100 B. 75 C. 50 D. 25 E. Can’t be determined 2. Yellow body (y), vermillion eye color (v) and miniature body (m) are recessive...
