Definitions:

Asexual Reproduction

A reproductive process that involves only one parent and produces offspring genetically identical to the parent.

Genetic Diversity

The total number of genetic characteristics in the genetic makeup of a species, contributing to variations within a population.

Random Segregation

The process during meiosis where chromosomes are randomly distributed to daughter cells, ensuring genetic diversity.

Homologous Chromosomes

Pairs of chromosomes in a diploid organism that have the same structure and sequence of genes but can have different alleles for the same genes, one inherited from each parent.
