Budding

Regeneration

Vegetative Propagation

A long string of coiled up DNA containing many many genes.

b)

A molecule that passes on hereditary information

c)

Instructions to make one trait or protein

d)

None of these

3.

A gene for a specific trait does not have a specific location on a gene. (In other words, it does not matter where a gene is located, as long as it is on the chromosome.)

False

4.

Select all that apply. One of the greatest advantages of sexual reproduction when compared to asexual reproduction is that in sexual reproduction

genetic diversity is created!

b)

many offspring can be created in a short amount of time.

c)

less energy is required.

d)

no mate is needed.

5.

True of False. Asexual reproduction only requires one parent while sexual reproduction typically requires two parents.

a)

True

b)

False

6.

Select all that apply. A mutation

a)

is a change in DNA, or instructions to make a protein.

b)

can be caused by the environment.

c)

can be caused by inherited genetics.

is always detrimental to (bad for) the organism

7.

Select all that apply. Some things I must do to do my best on today's assessment is to

Follow CHAMPS.

b)

Respect myself and my classmates.

c)

Raise my hand for help.

d)

Exhibit PRIDE

8.

In a class assignment studying heredity and genetics students rolled a dice to choose which trait was inherited. In this activity, the roll of the dice represented

a)

how an organism chooses the traits it wants to inherit.

b)

how traits are inherited in a random way.

c)

the inheritance of traits are planned.

d)

how parents can choose traits for their kids to inherit.

9.

True or False. All humans have 23 pairs of genes in their somatic cells. (Remember: Somatic cells include all cells except sex cells!)

a)

True

b)

False

10.

Sometimes the ________ inherited from each ___________ look the same, and sometimes they look different.

a)

chromosomes, genes

b)

parents, chromosome

c)

genes, offspring

d)

genes, parent

11.

typically one parent.

d)

typically two parents.

13.

Sex cells include egg and sperm. Another name for a sex cell is a

a)

neuron.

b)

gamete.

c)

somatic cell

d)

autonomic cell.
