Q. ______________ inversions reduce crossing over in ______________

View solution

Q. What are the results of pericentric inversion with single crossing over?

View solution

Q. In Drosophila Crossing over in paracentric region is lethal and leads to cross-over suppression. This leads to reduction in fertility.
