Which of the following is a TRUE statement about crossing over?

Crossing over occurs in both mitosis and meiosis I.
Crossing over occurs during prophase I of meiosis; because of crossing over, genetic variation in the resulting gametes is increased.
Crossing over occurs in telophase II of meiosis; it decreases the genetic variability in the gametes produced.

You have to select the correct statement this time...

abhisar · Answer

Statement C is indeed incorrect, crossing over increases the genetic variation.

rissyroo118 · Answer

i say A is correct

abhisar · Answer

Statement A is also incorrect as i just told ya that mitosis does not produces variations because crossing over does not take place in mitosis.
