Detailed explanation-1: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.

Detailed explanation-2: -Types of gametes produced by organism= 2n wherein n= number of loci for which the organism is heterozygous. The given diploid organism is heterozygous for 4 loci, types of gametes produced = 24= 16.

Detailed explanation-3: -During meiosis, the pairs of chromosomes separate and segregate randomly to produce gametes with one chromosome from each pair. Meiosis involves two nuclear and cell divisions without interphase in between, starting with one diploid cell and generating four haploid cells.

Detailed explanation-4: -4. Anaphase I: The pair of chromosomes are then pulled apart by the meiotic spindle, which pulls one chromosome to one pole of the cell and the other chromosome to the opposite pole.

Detailed explanation-5: -We produce gametes by meiotic cell division. We reduce the number of chromosomes to one half. And not just any half. Each of the four cells produced by meiosis has all of the 23 chromosomes, half a set of homologous pairs.
