Question

Crossing over results in ___.

• A. Separation of completely linked genes
• B. Separation of genes that are not linked
• C. Separation of incompletely linked genes
• D. None

Answer 1

The correct option is C

Separation of incompletely linked genes

During gametogenesis, genes present on the same chromosome may get assorted into different gametes as a result of crossing over. The genes that are present very close to each other or genes that are tightly linked on a chromosome rarely get separated. But genes that are linked, that is present on the same chromosome, but distant to each other, such that they can be exchanged between chromosomes, undergo recombination during crossing over.
