Answer:
option A
Explanation:
Cones provide colour vision while rods cells do not produce colour vision. Rods provide the vision in the dull light (darkness or night), whereas cones are known to give the vision during the day or bright light; Rod cells are more sensitive to light than cone cells and both do have visual pigments with the rod cells possessing rhodopsin and the cone cells having photo-opsins.

In meiosis, chromatids are made to exchange their genetic material during Prophase to allow the formation of offspring that are genetically different from their parents.
The process of exchange is called CROSSING OVER. And it occurs through a contact point known as Chiasma.
