GEN-3000 Study Guide - Midterm Guide: Chromosome, Meiosis, Karyotype
Document Summary
Chapter 7: linked genes, genes close together on the same chromosome and travel together during meiosis. Do not usually sort independently: morgan and sturtevant, morgan because of his fly lab, he found out genes are located on a chromosome, sturtevant morgan"s student who created the first gene linkage map. Ordering genes on a chromosome and figuring out how far apart they are: recombinant vs. nonrecombinant to figure out recombination we, recombinant recombinant gametes are brand new combinations, not seen in either parents a. i. From crossing over: nonrecombinant parental gametes. Arranging the chromosomes so they all fit depending how far they are from apart they are in relation to each other: limits once you get 50% recombination, it cannot be distinguished from independent assortment/linkage cannot be detected. 50% represents on different chromosomes: linkage groups used to get a chromosome map more than 50cm, testcrosses, 3-point mapping more efficient because order of genes can be established in a single cross a. i.
