Identify 2 reasons why offspring produced by sexual reproduction have more genetic variety

Crossing over and independent assortment

Explanation:

Meiosis can be described as a type of cell division which occurs in the sex cells. All the other cells of the body divide by mitosis.

During the process of meiosis, crossing over and independent assortment of chromosomes takes place which is the reason for the genetic variety produced in offsprings.

During crossing over, exchange of DNA segment between homologous chromosomes occur due to which genetic variations occur.

Also, the chromosomes assort independently in gametes during the process of meiosis due to which genetic variability is produced.
