Crossing over is a process that occurs in eukaryotic cells that are undergoing meiosis. Which of the following describes how
crossing over contributes to the role of meiosis?
It copies the genes in the DNA before gametes are formed.
It forms a unique number of chromosomes in each daughter cell.
It results in new diploid daughter cells that are exact copies of the parent cell.
It increases genetic variability by producing new combinations of genes in gametes.

Final answer:

Crossing over in meiosis increases genetic variability by generating new combinations of genes in gametes.


Explanation:

Crossing over is a crucial process during prophase I of meiosis where genetic material is exchanged between non-sister chromatids of homologous chromosomes. This exchange results in new combinations of genes on each chromosome, enhancing genetic variability in gametes. Through this mechanism, unique offspring with diverse genetic traits can be produced.
