HMH Unit 7 Meiosis & Genetic Variation

Front

What is fertilization?

Back

The fusion of a haploid egg and sperm.

Front

What causes genetic variation in meiosis?

Back

Crossing over of chromosomes.

Front

What does meiosis create?

Back

Gametes.

Front

Why do chromosomes assort independently, not genes?

Back

The chromosomes contain the genes; genes can't leave the chromosome.

Front

True or False: Meiosis results in identical cells.

Back

False.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, creating four haploid cells.

Front

What are gametes?

Back

Reproductive cells (sperm and eggs) that carry half the genetic information.

Front

What is crossing over?

Back

The exchange of genetic material between homologous chromosomes during meiosis.

Front

Define haploid.

Back

A cell that contains one complete set of chromosomes (n).

Front

Define diploid.

Back

A cell that contains two complete sets of chromosomes (2n).
