Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to _______ the number in the original cell.

The halving of the chromosome number counteracts a __________ of cells later in the life cycle of the organism.

In humans the diploid number is

Diploid is represented by

Most organisms are capable of combining chromosomes from two parents to produce

When chromosomes from two parents combine to produce offspring, the process is known as ____________ reproduction.

What type of cells are involved in sexual reproduction?

__________________ is when an ova and sperm join together.

What is another name for eggs?

Eggs are larger than sperm because they contain a lot of

Eggs are motile.

How many eggs are formed for each cell that undergoes meiosis?

What is the thick extracellular coat that plays a vital roles during oogenesis, fertilization, and pre-implantation development called?

What is the outermost layer of the ovum, which acts as a protective shield to the egg cell, called?

Sperm cells are motile.

Another name for sperm is

What is the tail region that consists of a long protrusion and helps the sperm swim to the non-motile egg called?

What does the mid-piece in the sperm contain?

The sperm contains large amounts of cytoplasm.

What stage does meiosis follow?

Meiosis only occurs in eukaryotic cells.

During meiosis, the number of chromosomes in each cell is reduced from diploid to haploid by separating _________________ pairs of chromosomes.

What phase is called the "Reduction Division"?

When homologous pairs of chromosomes come together before meiosis begins this is event is called

The chromatid pair up with their homologous pair, forming a

What is it called when the tetrad contains 2 original homologous chromosomes.

Crossing-over is an important process which results in ____________________ by producing a new mixture of genetic material.

Crossing over occurs only in what phase?

Spindle fibers pull one member from each pair to opposite ends of the cell. This random separation of the homologous chromosomes is called

__________________ is the exchange of genes between a pair of homologous chromosomes.

In the testes, meiosis is involved in the production of male gametes known as sperm cells or

In the development of sperm cells, a diploid reproductive cell called spermatorgonium divides meiotically to form four haploid cells called

Each spermatid develps into a mature sperm cell in the process of

The production of sperm cells is called

What is the production of a mature egg cell called?

What are the three smaller products at the end of oogenesis called?

Which of the following is true about meiosis?

Which statement describes the overall process of meiosis?

What kind of cell(s) does meiosis begin with?

What are cells produced by meiosis called?

How many chromosomes does a human haploid cell have?

How many daughter cells are produced at the end of meiosis I?

How many daughter cells are produced at the end of meiosis II?

Are the cells haploid or diploid at the end of metaphase I?

Are the cells haploid or diploid at the end of anaphase I?

Are the cells haploid or diploid at the end of metaphase II?

Are the cells haploid or diploid at the end of anaphaseII?

Cytokinesis is when

Cells that have two homologous sets of chromosomes are

Interphase is when

Cells that have a single set of chromosomes are

Centrioles move to the opposite sides of the cell while single chromosomes line up at the center of the cell.

Chromatin condenses into chromosomes, the nucleus breaks down, the centrioles move apart, the spindle forms, and homologous chromosomes become physically connected.

Chromosomes are pulled apart at the centromere with each sister chromatid moving to opposite sides of the cell.

Spindle fibers dissolve and nuclei form around each set of chromosome in two daughter cells.

Homologous chromosome pairs are pulled apart and move to opposite sides of the cell.

The nucleus breaks down, the centrioles move apart, and the spindle forms.
