The term used for crossing over is recombination<span>. ... Finally, for two </span>genes<span> are right next to each other on the chromosome crossing over will be a very rare event. Two types of gametes are possible when following </span>genes<span> on the same chromosomes. If crossing over </span>does<span> not </span>occur<span>, the products are parental gametes. Hope this helps!!</span>
