Meiosis Phases

Front

What is the first phase of meiosis?

Back

Prophase I

Front

How many divisions occur in meiosis?

Back

2

Front

What is the purpose of meiosis?

Back

The purpose of meiosis is to produce gametes with half the number of chromosomes.

Front

What happens during prophase I of meiosis?

Back

Homologous chromosomes pair up and undergo crossing over.

Front

What is the significance of crossing over in meiosis?

Back

Crossing over in meiosis promotes genetic diversity by exchanging genetic material between homologous chromosomes.

Front

Which phase of meiosis involves the alignment of homologous chromosomes at the metaphase plate?

Back

Metaphase I

Front

What is the result of meiosis in terms of chromosome number?

Back

Haploid cells with half the number of chromosomes

Front

Describe the events that occur during anaphase I of meiosis.

Back

Homologous chromosomes separate and move to opposite poles of the cell.

Front

What is the difference between meiosis I and meiosis II?

Back

Meiosis I involves homologous chromosomes pairing up and crossing over, while Meiosis II involves sister chromatids separating.

Front

Explain the importance of genetic variation resulting from meiosis.

Back

Genetic variation resulting from meiosis is important because it leads to the creation of genetically diverse gametes, which increases the potential for offspring to inherit different combinations of genes. This diversity is essential for evolution and adaptation to changing environments.
