BIOL 2081C Lecture Notes - Lecture 13: Hypoxanthine-Guanine Phosphoribosyltransferase, Linkage Disequilibrium, Centimorgan
Document Summary
Scientists were able to map the locations of genes to specific regions of chromosomes. Through breeding strategies, the numbers of offspring with parental and non-parental traits revealed the distance between genes on a chromosome. The los are the same for lecture 12 and 13, but the pre-class assignments differ. Be sure to prepare for class by completing each day"s pre-class assignment. Reading assignment: hartl, sections 5. 1 - 5. 3, and 5. 5. Recombination will likely happen more between hprt and a 20 cm gene because dxys1 and p8 gene are linked. Therefore when these will cross over it wouldn"t be recombinant whereas 20cm gene isn"t linked to anything which will likely create recombinant genes. But i"m not confidently sure in my answer: a) more likely, b) less likely, consider a trihybrid individual, where genes a, b, and d are on the same chromosome 1 click here for diagram .
