Solution

The correct option is B 050%
Cross over result in independent assortment and formation of recombinnation of genes .
When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%. As 50% of gametes produced always have parental combination of genes, cross over can only vary from 0-50%
So, the correct option '0-50%'.
