Question
What is independent assortment, when does it occur and what is its purpose?
Solution
Independent assortment is a basic principle of genetics developed by a monk named Gregor Mendel in the 1860s. Mendel formulated this principle after discovering that different traits had an equal opportunity of occurring together.
The principle of independent assortment states that the alleles for a trait separate when gametes are formed. These allele pairs then randomly unite at fertilization.
This principle is a result of meiosis I, which is a type of cell division. During meiosis I, homologous chromosomes line up in the middle of the cell and then get pulled apart so that each new cell only has one copy of each chromosome. Because the chromosomes can line up in different ways, there are many different combinations of chromosomes that can end up in the gametes. This is when independent assortment occurs.
The purpose of independent assortment is to increase genetic diversity within a species. Because the chromosomes separate independently, the traits they carry can mix in new ways from generation to generation. This helps to ensure that not all offspring are identical, which can be beneficial for the survival of the species.
