What is the end result of crossing-over during the first stage of meiosis?

-the paternal DNA only is copied onto the chromatids
-the chromatids are identical to each other
-the chromatids contain the maternal DNA only
-the chromatids become non-sister (non-identical) chromatids

Sagot :

Answer:

The chromatids contain the maternal DNA only.

Explanation:

They must contain half the original number of chromosomes. It must contain only one chromosome in place of each homologous pair of chromosomes, so it is endowed with either the maternal or the paternal copy of each gene but not both.
