Introduction
Haploid Versus Diploid
Overview
Meiosis 1
Vocab Review
100

The number of chromosomes humans get from each parent.

What is 23 chromosomes?

100

A cell with half the number of chromosomes

What is a haploid cell?
100
This is what Meiosis is divided into.
What are Meiosis I and Meiosis II?
100
This is the number of cells that are present at the end of Meiosis 1.
What are 2?
100

These pull apart the chromosomes during anaphase.  These were represented by the yellow pieces in the lab yesterday.

What is the spindle fiber?

200
The term used to describe egg and sperm cells.
What is gamete?
200
This is what a sperm is (haploid or diploid).
What is haploid?
200

This must happen before Meiosis begins.

What is DNA replication/Interphase?

200
This is a process that occurs during Prophase 1, only during Meiosis.
What is crossing over?
200
This is the number and type of cells made at the end of Meiosis 2.
What are 4 genetically unique haploid gametes?
300
The term used to describe the diploid cell created after the egg and sperm fuse.
What is a zygote?
300

A cell with sets/pairs of chromosomes.

What is a diploid cell?

300

Meiosis I can be divided into ____________, but Meiosis II can be divided into _____________.

What are Prophase, Metaphase, Anaphase, and Telophase (for both)?

300
This is what happens during crossing over.
What is the exchange of DNA between homologous chromosomes?
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
The type of cells made during meiosis.
What are gametes?
400
This is what a zygote is (haploid or diploid).
What is diploid?
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?
400
This is the number of divisions during all of meiosis.
What are 2 divisions?
400

This is made possible by the process of meiosis and sexual reproduction.

What is genetic variation?

500
The term used to describe a pair of chromosomes.
What are homologous chromosomes?
500

Organisms must have certain numbers of chromosomes to function properly.

Why is chromosome number important?

500

4 cells with only half the number of chromosomes as the original cell so that when two of these cells join the offspring can have the right amount of chromosomes

What is the result of meiosis and why is this important?

500
This is the term used to describe different forms of a gene.
What is an allele?
500

This is the name of the process the organisms go through to make identical cells in order to grow and develop.

What is mitosis?
