120
3.

A human has 46 chromosomes in their somatic (body) cells. How many chromosomes are found in the haploid cells?

a)

46

b)

92

c)

23

d)

12

4.

Are somatic cells diploid or haploid cells?

a)

Haploid

b)

Diploid

5.

How does the number of chromosomes in the starting cell compare to the number of chromosomes in the cells at the end of meiosis?

a)

The number of chromosomes is cut in half

b)

The number of chromosomes doubles

c)

The cells become diploid

d)

The number of chromosomes stays the same

6.
What type of cells are produced in meiosis?
a)
Body Cells
b)
Gametes
c)
Hair cells
d)
Liver cells
7.

Which of the following best describes the daughter cells that result at the end of meiosis II?

a)

There are four diploid daughter cells

b)

There are two diploid daughter cells

c)

There are two haploid daughter cells

d)

There are four haploid daughter cells

8.

Are the cells produced in meiosis identical or unique?

a)

Identical

b)

Unique

9.

The model shows homologous chromosomes during prophase I of meiosis. This process results in more genetic diversity in the species by creating new combinations of genes. What process is being illustrated in the model?

a)

Independent Assortment

b)

Interphase

c)

Random Fertilization

d)

Crossing Over

10.

Why do diploid cells always have an even number of chromosomes?

a)

The diploid cells contain pairs of chromosomes, one from each parent, so it is always an even number.

b)

It is random; some other organisms have an odd number of chromosomes in their diploid cells.

c)

The haploid chromosome number is always even so that when division occurs each new cell gets the same number of chromosomes.

d)

Chromosomes double every time the cell divides, so after meiosis the number is even

11.
In sexual reproduction, what is the source of the genetic material in a zygote? 
a)
 An egg cell only
b)
A pollen and a sperm cell
c)
 A sperm cell only 
d)
An egg cell and a sperm cell
12.
Which species can produce offspring that are genetically different from their parents?
a)
A species that has few variations 
b)
A species that reproduces asexually 
c)
A species that reproduces sexually 
d)
A species that competes with a similar species
13.

The pair of chromosomes that contain the same genes (but may be coded differently) and are inherited from a male and female parent are termed ___.

a)

gametes

b)

alleles

c)

zygote

d)

homologous chromosomes

14.
After meiosis II the daughter cells will contain ____ chromosomes if the original cell contained 78.
a)
78
b)
39
c)
23
d)
