4. What is crossing over?How does it increase the genetic diversity of offspring? This activity was completed __ (instructor signature) Overview: You will be using a computer simulation to identify similarities and differences between mitosis an meiosis You will uter simulation to identify similarity these concepts and why they occur.

Crossing over is a process that occurs during prophase I of meiosis, where homologous chromosomes pair up and exchange segments of their genetic material. This exchange of genetic material between non-sister chromatids results in new combinations of alleles on each chromosome.<br /><br />Crossing over increases the genetic diversity of offspring by creating new combinations of genes that are different from those found in either parent. This genetic variation is important for evolution and adaptation, as it provides a wider range of traits that can be beneficial in changing environments.
