Please discuss during which phases of Meiosis Mendel’s Law of Segregation, and the law of independent assortment take place.
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.
Mendel's Law of Independent Assortment states that:
the members of a pair of homologous chromosemes assort independently of each other during gamete formation
none of these
the members of a pair of homologous chromosomes separate from each other during gamete formati
different pairs of homologous chromosomes assort independently of each other during gamete formation
different pairs of homologous chromosomes separate from each other during gamete formation
