A Model Suggestion to Prove That “The Role of Independent Assortment in Genetic Diversity is More Important Than Crossing Over”

Ayla Karataş,Canan Laçin Şimşek,Zübeyde Akan Kumbıçak.


Abstract

The most important event that causes genetic diversity in sexual reproduction organisms is meiosis and impregnation. Due to independent assortment and crossing over which happens in meiosis, the possibility of many different variations of gametes from same parents occurs. However, students try to explain genetic diversity that occurs by meiosis just with crossing over and they don’t mention the role of independent assortment and impregnation. This study attempted to emphasize the role and importance of independent assortment in genetic diversity by a model which was made by cartons. The role of crossing over and impregnation was not discussed because the main purpose of this model is to highlight the role of independent assortment. It is hoped that by this model, understanding both the fundamental cause of genetic diversity and the law of Mendel will be easier.

Key words: Genetic diversity, Variation, Meiosis, Independent assortment, Crossing over
