Crossing over

Crossing over Definition
At the tetrad phase, the improvement of novel mixtures because of section transfer with the aid of using non-sister chromatids of homologous chromosomes is referred to as crossing over
Factors that affect crossing over
1. Temperature: High and low temperatures increases the frequency of crossing over
2. Radium rays: This increases cross-over as well
3. Age: Older women have a higher likelihood of crossing over
Importance
1. It is used to generate linkage maps or genetic maps
2. Crossover produces recombinations or novel mixtures which adjust the genetic pool with the aid of using converting gene frequency and subsequently offer a pathway for evolution.
