Question

During meiosis, genetic diversity results from which of the following processes? More than one answer may be correct.

replication of the cell's DNA
recombination via crossing over
independent assortment of chromosomes

Answer 1

The answer are:

recombination via crossing over
independent assortment of chromosomes


During meiosis, a cell separates into four daughter cells called gametes that are utilized amid sexual propagation. The hereditary differing qualities come about because of the procedures of recombination by means of the traverse and the free variety of chromosomes.

Answer 2

Ans.

Genetic diversity can be described as total genetic characteristics in the genetic makeup of a particular species. It can be increased by the meiotic cell division, a type of cell division that takes place in gamete-forming cells.

During meiosis, processes that can cause genetic diversity include recombination and independent assortment of chromosomes. Recombination involves 'exchange of chromosome segments between homologous pairs of chromosomes with each other'. It leads to formation of gametes with different genetic makeup and causes genetic diversity.

Independent assortment involves random distribution of homologous chromosomes during anaphase I of meiosis. It results in formation of gametes with unique chromosome combinations and cause genetic diversity.

Thus, the correct options are 'recombination via crossing over' and 'independent assortment of chromosomes.'
