2.

A dog gives birth to 5 puppies. What percentage of the chromosomes does each puppy share with the mother? (HINT - Divide the total percentage by the number of puppies.)

a)

20%

b)

50%

c)

100%

d)

0%

3.

Complex molecule that carries genetic information that defines an organism's traits. It is stored in the nucleus.

a)

DNA

b)

RNA

c)

Protein

d)

Glucose nucleic acid (GNA)

4.

B = brown eyes

b = blue eyes

What is true about these two brothers that have brown eyes? James - Bb Carl - BB

a)

A dominant trait

b)

One has genetype and the other Bb

c)

James inherited a dominant and recessive trait and can have green eyes or brown eyes while Carl inherited only dominant traits leading him to have brown eyes.

d)

Carl inherited a dominant and recessive trait and can have green eyes or brown eyes while James inherited only dominant traits leading him to have brown eyes.

5.

What is the difference between sexual and asexual reproduction?

a)

Sexual reproduction makes identical offspring with only a single parent while Asexual reproduction needs a partner to make an offspring

b)

Asexual reproduction needs a partner for an offspring

c)

Sexual reproduction involves a partner to make an offspring while Asexual reproduction does not need a partner and makes identical offspring

d)

There is no difference. They are the same thing

6.

How is a heterozygous represented? How is a homozygous represented?

a)

BB and BB

b)

Heterozygous - bB Homozygous - Bb

c)

Heterozygous and Homozygous cannot be represented

d)

Heterozygous - Bb Homozygous - BB

7.

An offspring inherit 23 chromosomes each from its mom and dad. If the offspring turns out to look more like the dad than the mom, how many chromosomes did the offspring inherit from the mom? Explain

a)

47 - The offspring inherited more chromosomes from the dad than the mom causing the total chromosomes to increase.

b)

24 - The offspring inherited more traits from their dad than their mom.

c)

18 - The offspring inherited less chromosomes from the mom to look like the dad.

d)

23 - Even if the offspring looks like one over the other, it would still have 23 chromosomes from its mom. The dad would have more dominant traits than the mom.

8.

Gregor Mendel

b)

Albert Einstein

c)

Charles Darwin

d)

Carl Linnaeus

9.

What is the difference between phenotype and genotype?

a)

They are both the same. They are the observable features of an organisms.

b)

The difference between phenotype and genotype is that the phenotype is the observable characteristics of an organism. The genotype is the collection of genes within n organism

c)

The difference between phenotype and genotype is that the phenotype is the collection of genes within an organism and the genotype is the observable characteristics of an organism.

d)

A physical characteristic of an organism

10.

Remember Gregor Mendel? What was the organism that he studied first? What were the characteristics that he studied about the organism

a)

Food; taste, looks, shape, color

b)

Pine tree; height, seed color, seed shape, seed coat color, and pod shape

c)

Pea Plants; height, seed color, seed shape, seed coat color, pod shape

d)

Bacteria; function, shape, size,
