Briefly describe Mendel’s rule of inheritance: segregation and independent assortment
Explain how the mechanics of meiosis and the movement of homologous chromosomes underlie Mendel's principles of segregation and independent assortment.
When Gregor Mendel was working in the mid 1800s, scientists had not yet discovered chromosomes or meiosis. However, we now understand how Mendel's principles are rooted in the events of meiosis. As an example of this, state Mendel's principle of independent assortment and explain how it relates to independent assortment in meiosis.
