Answer
The phase of meiosis depicted in diagram A is Prophase. This is characterized by the condensation of chromosomes, and the pairing of homologous chromosomes occurs, forming tetrads.

Answer
The phase of meiosis depicted in diagram B is Anaphase. In this stage, homologous chromosomes are pulled apart and moved towards opposite poles of the cell.
Step 3
Draw a labelled diagram to show the cells that will be formed at the end of meiosis from the cell in diagram C.

Answer
The cells formed at the end of meiosis from diagram C will consist of four haploid cells, each containing half the original number of chromosomes. The diagram should include labels such as:
Cell membrane
Nucleus
Nucleoplasm
Chromosome (showing chromatid)
Cytoplasm
Ensure that each cell is distinctly represented to illustrate their haploid nature.
