Question

Product of sexual reproduction generally generates

• A. Large biomass
• B. Lower viability of seeds
• C. Prolonged dormancy
• D. New genetic combinations leading to variations

Answer 1

Answer: (D)

New genetic combinations leading to variations

Answer 2

Sexual reproduction produces new genetic combinations having variations from the earlier genetic combinations. The variation in the offspring characteristics is dependent on the genetic combination of either parent.

In the case of Eukaryotes, during meiosis, genetic recombination leads to a collection of genetic information through sexual reproduction. This is passed via inheritance from parent to offspring. The variation is advantageous as it allows certain individual populations to survive in conditions of changing environmental conditions. During sexual reproduction:

• There is a creation ofhaploid gametes.
• Meiosis is a specialized cell divisionmethod that produces gametes.
• This requires reductional division and crossing over.
• Chromosomepairs are shared during cross-over between non-sister chromatids.
• New genetic combinations are produced from the cross-over.

The other options, Large biomass, Longer viability of seeds, and Prolonged dormancy are not factors that are linked to sexual reproduction as these are dependent on the nutrient intake, surrounding conditions etc.
