Question

The percentage of recombinant gametes is always _______ the percentage of the number of meiotic cells that had a single crossover?

1) greater than
2) less than
3) equal to
4) cannot be determined

Answer 1

The percentage of recombinant gametes is always greater than the percentage of meiotic cells that had a single crossover. Option 1.

Step-by-step explanation:

The percentage of recombinant gametes is always greater than the percentage of meiotic cells that had a single crossover.

Recombination occurs during meiosis, and it involves the exchange of genetic material between homologous chromosomes. This process results in the formation of gametes with new combinations of genes.

When a single crossover occurs during meiosis, only a portion of the genetic material is exchanged. However, in the gametes, the exchanged segment is considered as a whole. Therefore, the percentage of recombinant gametes is always greater than the percentage of meiotic cells that had a single crossover.

So Option 1 is correct.
