Telophase.

Front

What is the end result of meiosis in terms of chromosome number?

Back

Haploid cells.

Front

Which event takes place in meiosis II but not in meiosis I?

Back

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes during cell division.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes, while haploid cells have one set.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs during the S phase.

Front

What is crossing over and when does it occur?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis.
