The chromosomes are first replicated during interphase. In meiosis I, the homologous chromosomes first pair (synapse) with one another. During synapses, pieces of the chromatids can be exchanged between the homologues. The homologous chromosomes are separated by the end of meiosis I.

In meiosis II, the chromatids are separated from each other, four haploid daughter cells each with single stranded chromosomes are formed.

If it is a male, four sperm are formed. In females, one egg and four polar bodies are formed.

What happens to the remaining chromosomes from the last division in meiosis?

In meiosis all the chromosomes are incorporated into sperm cells whereas production of an unfertilized egg results in the leftover chromosomes incorporated into polar bodies.


What happens to the number of chromosomes during meiosis?

During meiosis, the number of chromosomes is halved. This process results in the formation of sex cells (sperm and egg) with half the number of chromosomes as the parent cell.


Name and briefly describe the stages of the two meiotic divisions of meiosis?

The two meiotic divisions are called meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing-over before separating, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in four daughter cells, each with a unique combination of genes.


How many times do chromosomes make copies of themselves during meiosis?

Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.


The pairing of homologous chromosomes before nuclear division happens in what type of cell division?

The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
