Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Choose the right option for meiosisI. Four haploid cells are producedII. Produces gametes and genetic variation in organismsIII. Responsible for growth and repair
A
I
B
I AND II
C
I, II AND III
D
I AND III
Explanation: 

Detailed explanation-1: -Reduction to Haploid This means that it is equally likely for a given chromosome to be distributed to either of the two daughter cells. By shuffling the genetic deck in this way, the gametes resulting from meiosis II have new combinations of maternal and paternal chromosomes, increasing genetic diversity.

Detailed explanation-2: -The exchange of genetic information between homologous chromosomes also induces variation. The random orientation of sister chromatids in meiosis II also generates genetic variation.

Detailed explanation-3: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-4: -Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
