Mapping linked genes in Drosophila melanogaster using data from the F2 generation of a dihybrid cross They did agene linkageanalysis on families with two homosexual brothers, typing for 22 DNA markers on the X chromosome. Genes, hormones, and sexuality ...
segregation of the trait and markers linked to it are measured. Thisstrategy requires several rounds of mapping and an extensive segregating population to be able to obtain sufficient genetic resolution to identify a small number of candidate genes involved in the trait of interest (Fleury et al....

Thus, structural genes are linked to an operator gene in a functional unit called anope...
Comparative analysis of mouse-human hybrids with rearranged chromosomes 1 by in situ hybridization and southern blotting: High-resolution mapping of NRAS, NGFB, and AMY on human chromosome 1 The human protooncogene NRAS and the genes for the 尾-subunit of nerve growth factor (NGFB) and for amyl...
Linkage, Crossing Over and Gene Mapping Chapter 7 Linkage, Crossing Over and Gene Mapping Genes on the same chromosome are said to be “linked” Because of crossing over during meiosis, linkage is usually less than 100% Recombination frequencies are used to map the positions of genes on chromos...
