Meiosis

Introduction

100

The number of chromosomes you get from each parent.

What is 23 chromosomes?

200

The term used to describe body cells made during MITOSIS.

What is a somatic cell?

300

The term used to describe the diploid cell created after the egg and sperm fuse.

What is a zygote?

400

The type of cells made during meiosis (not specific to gender).

What are gametes?

500

The term used to describe a pair of chromosomes inherited from each parent.

What are homologous chromosomes?

Haploid Versus Diploid

100

The number and letter combinations used to describe haploid and diploid.

What are n (haploid) and 2n (diploid)?

200

A sperm cell is  said to be this ploidy.

What is haploid?

300

A cell with 2 sets of chromosomes. Example: fertilized zygote. 

What is a diploid cell?

400

In Meiosis I, cells are haploid or diploid?

What is diploid?

500

A fertilized zygote has a set of each chromosome originating from each parent therefore the gametes have to be this.

Why are gametes haploid?

Overview

100

This is what Meiosis is divided into.

What are Meiosis I and Meiosis II?

200

This must happen before Meiosis begins.

What is DNA replication?

300

The 8 stages of meiosis

What are Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telophase II?

400

This is the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.

What is cytokinesis?

500

The stage in the development of a cell following mitosis or meiosis, during which the nucleus is not dividing.

What is Interphase?

Meiosis 1

100

2 cells.

How many cells are present at the end of meiosis 1?

200

This is a process that occurs during Prophase 1, only during Meiosis. It creates extra genetic diversity. 

What is crossing over?

300

This is what happens during crossing over.

What is the exchange of DNA between homologous chromosomes?

400

Chromosomal structure allowing crossing over.

What is a tetrad?

500

This law describes the fact that chromosomes are separated into chromatids randomly and separately for each chromosome. 

What is the Law of Independent Assortment?

Meiosis 2

100

One of these is NOT part of the chromosome. spindle, centromere, or chromatid

What is the spindle?

200

This is the number and type of cells made at the end of Meiosis 2.

What are 4 genetically unique haploid gametes?

300

A cell with a diploid number of 24 undergoes meiosis, so this is the number of chromosomes in each daughter cell.

What is 12?

400

After meiosis, are gametes genetically identical or different. Explain why. 

What is genetically different because the chromosomes have crossed over and independently assorted. 

500

How are Anaphase I and Anaphase II different?

Anaphase I separates homologous chromosomes, Anaphase II, the sister chromosomes are separated.
