What is the process that allows mixing the combinations of genes in a single chromosome,resulting in a virtually infinite possible combination of genes?

Question

Quizplus · Accepted Answer

Crossing over is a process that allows mixing the combinations of genes in a single chromosome during meiosis. It involves the exchange of genetic material between homologous chromosomes, resulting in new combinations of alleles on each chromosome. This process results in a virtually infinite possible combination of genes, making each individual unique. A is incorrect as sampling from a large genetic pool does not necessarily involve mixing genes within a chromosome. B is incorrect as gamete swapping is not a recognized biological process. D is incorrect as mitosis does not involve the mixing of genetic material from different chromosomes.
