Linkage crossing over

NettetGenes generally tend to stay in parental combination, except in cases of crossing over. 4. The distance between linked genes in a chromosome determines the strength of linkage. Genes located close to each other show stronger linkage than that are located far from each other, since the former are less likely to enter into crossing over. Linkage ...
