How does the presence of coal in Antarctica provide evidence for continental drift?

There have been glacial deposits founded in the tropics and coal founded in Antarctica. This supports the theory of the Continental Drift, because coal originates from tropical plants, which can only be founded in the tropics. Additionally glacial deposits can only come from Antarctica, proving the theory.

Hope it helps :)

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
