Question

Crossing over plays a major role in producing which of the following outcomes among offspring?

विकल्प

• Reduced chromosome number

• Identical genetic makeup

• Variation

• Chromosome duplication

Answer 1

Crossing over is an important event of genetic recombination and plays a major role in producing variation among offspring. By creating new combinations of genes in gametes, crossing over ensures that offspring inherit unique genetic combinations, increasing diversity in a population.
