Front

What is formed when a homologous pair of chromosomes associates during Prophase I?

Back

Bivalent

Front

How many diploid chromosomes do humans have?

Back

23 pairs

Front

What occurs during Metaphase II?

Back

Pairs of sister chromatids align at the equator.

Front

What is the term for the exchange of genetic material between homologous chromosomes during meiosis?

Back

Crossing over

Front

What is the main purpose of meiosis?

Back

To produce gametes with half the number of chromosomes.

Front

What is a homologous chromosome?

Back

Chromosomes that are similar in shape, size, and genetic content.

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 is non-disjunction?

Back

The failure of homologous chromosomes or sister chromatids to separate properly during cell division.

Front

What is the role of chiasmata during meiosis?

Back

Chiasmata are points where homologous chromosomes exchange genetic material.
