Question

Are these 4 cell’s genetically identical or genetically different

Answer 1

These four cells are genetically different.

Explanation:

The four cells that are marked here are the cells that are taking part in meiosis II. The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.

The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. So their product cells that are produced from the meiosis II are also genetically different.
