Meiosis Review

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes of the original cell.

How many chromosomes do daughter cells have if the parent cell has 30 chromosomes?

Back

15 chromosomes.

Front

What separates during Anaphase II?

Back

Sister chromatids separate during Anaphase II.

Front

What lines up on the equatorial plane during Metaphase II?

Back

Single chromosomes (made up of 2 sister chromatids) line up on the equatorial plane.

What phase follows Metaphase I?

Back

Anaphase I follows Metaphase I.

Front

What is the end result of meiosis?

Back

The end result of meiosis is four haploid daughter cells, each genetically distinct from one another and from the parent cell.

Front

What is a tetrad?

Back

A tetrad is a structure containing four chromatids that forms during meiosis, consisting of a pair of homologous chromosomes.

Front

What occurs during Prophase I?

Back

During Prophase I, homologous chromosomes pair up and exchange segments through a process called crossing over.

What is the difference between meiosis I and meiosis II?

Back

Meiosis I is a reductional division that separates homologous chromosomes, while meiosis II is an equational division that separates sister chromatids.

Front

What happens during Telophase I?

Back

During Telophase I, the cell divides into two daughter cells, each with half the number of chromosomes.
