Cross-pollination has several advantages; It introduces genetic diversity in the plants which makes them resistant to diseases. It gives the hybrid progenies i.e. more viable and resistant offspring with new desirable characters. It helps in evolution. Undesirable characters of the plants can be eliminated by the cross-pollination method.
So, the correct answer is option B.

A scientist conducted a crossing experiment with Drosophila. From the experimental results he concluded that crossing over occurs in females but not in males. From this information, choose the correct statement regarding the types of gametes produced by the female and the male flies. The male and female both have the same genotype (AB/ab).

When a white eye Drosophila male(XrY) is crossed to a red eye female (XRXR), in the F2 generation all the females are red eyed and 50% males are white eyed. In a criss cross test, when a white eyed female(XrXr) is crossed to a red eye male(XRY), the F1 generation off spring had white eyed males while the female offspring had red eyes. Instead of crossing of a white eyed female (XrXr) to a red eyed male (XRY), white eye female (XrXr) to white eye male (XrY) is crossed, the F1 generation will have the following phenotypes and genotype.
