NettetCrossing over refers to the interchange of parts between non-sister chromatids of homologus chromosomes during meiotic prophase (pachytene). In other words, crossing over results from exchange of genetic material between non-sister chromatids involving breakage and reunion at precise point. NettetCross overs allow geneticists to work out the relative positions of genes on chromosomes. The crossover values are used to create chromosome maps. e.g. 11 Sex Linkage Homologous chromosomes are normally identical in appearance and are called autosomes. Exceptions to this are the sex chromosomes called heterosomes. NettetA linkage map is a map based on the frequencies of recombination between markers during crossover of homologous chromosomes.
