Question

Choose the correct answers from the alternatives given.
The genetic diversity arising from meiosis results from

• A. replication of DNA during interphase
• B. mixing of maternal and paternal chromatids during meiosis II
• C. crossing over during prophase
• D. both (b) and (c)

Answer 1

The correct option is C crossing over during prophase

Crossing over is the phenomenon in the prophase of meiosis in which the paternal and maternal chromosomes exchange segments with each other leading to variability in the offspring due to shuffling of genes.
Crossing over results in variability in the species despite having the same genes from the parents.

So, the correct option is 'crossing over during prophase'.
