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

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

In Drosophila only females undergo recombination. In the case of egg formation out of the 4 meiotic products, only one forms the egg and the 3 other forms the polar body. Thus, the cross over suppressed gamete simply forms the polar body so doesn’t affect fertility.

Statement : On an average, about twenty people are run over by trains and die every day while crossing the railway tracks through the level crossing.

Courses of Action :
I. The railway authorities should be instructed to close all the level crossings.
II. Those who are found crossing the tracks, when the gates are closed, should be fined heavily.
