4

Front

What is the correct order of the cell cycle?

Back

Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis

Front

What type of cells are human eggs and sperm, and how many chromosomes do they have?

Back

Haploid, 23

Front

If a male shark has 40 chromosomes in each of its sex cells, how many chromosomes are in its body cells?

Back

80

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the main purpose of meiosis?

Back

The main purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes, ensuring genetic diversity through sexual reproduction.

Front

What is crossing over in meiosis?

Back

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

Front

What are homologous chromosomes?

Back

Homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells contain two complete sets of chromosomes (2n), while haploid cells contain only one set (n).
