Define linkage in biology class 12
WebSolution. Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Two genetic markers that are physically near to each other are unlikely to be separated into different chromatids during the chromosomal crossover and are therefore said to ... WebTypes of linkage. 1. The genes located on the same chromosome do not separate and are inherited together over the generations due to the absence of crossing over. 2. Complete linkage allows the combination of parental traits to be inherited as such. 3. It is rare but has been reported in male Drosophila and some other heterogametic organisms. 1.

Sex-linked traits show interesting inheritance patterns in part because females have two copies of each X chromosome, but males only have one. This inheritance pattern means that a male with the recessive allele will always show the recessive trait, because ...
