Answered by jagadeep72

Cytological basis of crossing over. ... Crossing over is a process that produces new combinations of genes by exchanging segments between non-sister chromatids of homologous chromosomes normally reciprocally but sometimes unequally.

Answered by Arslankincsem

The cytological basis of crossing over is to form new gene combinations where the chromatids that are non-sisters exchange segments in a reciprocal manner and at many times non-equally.

The chromosomal pars get interchanged to form a new variety of genes.

This was termed as a crossover by Morgan and it occurs in the DNA levels as well as the chromosomal levels.

The physical distance of the genes is a factor for the crossover.
