Crossovers

In genetics, crossovers refer to the process during meiosis where homologous chromosomes exchange segments of genetic material. This exchange creates new combinations of genes, increasing genetic diversity within a population. Think of it like swapping sections of two similar books to produce two new stories, each with a mix of original content. Crossovers are random and essential for evolution, as they generate unique genetic traits that can be passed on to future generations. This process contributes to the variability observed in offspring, which is fundamental to biological adaptation and diversity.
