23
30 sec
Q.
This occurs during meiosis when homologous chromosomes line up randomly at the metaphase plate, leading to different combinations of chromosomes in gametes.
24
30 sec
Q.
During meiosis, this involves the exchange of genetic material between homologous chromosomes. This creates new combinations of alleles on a chromosome, contributing further to genetic diversity.

Q.
This refers to the chance nature of which sperm fertilizes which egg during sexual reproduction. With millions of sperm and eggs, the combination that leads to fertilization is essentially random,
