AP Bio Topic 5.2 Meiosis and Genetic Diversity Flashcard

Front

What phase does independent assortment take place?

Back

Metaphase I

Front

What distinguishes Prophase I of Meiosis from Prophase of Mitosis?

Back

Homologous chromosomes pair up.

Front

What is the result of Meiosis II?

Back

Four haploid daughter cells.

Front

What is a karyotype?

Back

An organized picture of all of an organism’s homologous chromosome pairs lined up with each other.

Front

What are the main differences between mitosis and meiosis?

Back

Number of divisions, number of daughter cells, and genetic variation.

Front

Define meiosis.

Back

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

Front

What is the purpose of meiosis?

Back

To produce gametes for sexual reproduction.

Front

What occurs during Prophase I of meiosis?

Back

Homologous chromosomes pair up and exchange genetic material through crossing over.

Front

What is crossing over?

Back

The exchange of genetic material between homologous chromosomes during Prophase I.

Front

How many times does DNA replicate during meiosis?

Back

Once, before Meiosis I.
