Front (Question)

Which traits (eye color, tongue roll, finger cross, earlobes, hairline, hand clasp, and PTC tasting) are inherited from parents?

Back (Answer)

Eye color, hairline, earlobes, PTC (100%) Tongue roll, finger cross, hand clasp (partial)

Front (Question)

True/False: Most traits are impacted by the environment

Back (Answer)

True

Front (Question)

Is the classroom an accurate representation of a larger population (a school or community)? Why or why not?

Back (Answer)

No… sample size was too small and too similar

Front (Question)

Why do we study fruit flies or plants?

Back (Answer)

• Short generation time (birth to reproductive maturity) • Produce many offspring • Easy to obtain/maintain • Have many observable traits • Ethical

Front (Question)

In generation I, two plants were homozygous green and two were albino (yellow/white). What is the probability of a Gen II plant being green?

Back (Answer)

100%

Front (Question)

What does connective tissue do?

Back (Answer)

Provides connections from tissue in the body

Front (Question)

What are the pros about asexual reproduction?

Back (Answer)

• Rapid + efficient - Doesn’t rely on a mate

Front (Question)

What is the con about asexual reproduction?

Back (Answer)

• No genetic diversity - risky for a species

Front (Question)

What is an example of asexual reproduction in a unicellular organism?

Back (Answer)

Bacteria: copy genetic information and divide

#10

Front (Question)

What is an example of asexual reproduction in a multicellular organism?

Back (Answer)

Hydra: budding: offspring grow directly from the parent and break off when they mature

#11

Front (Question)

What is the pro about sexual reproduction?

Back (Answer)

• Genetic diversity

#12

Front (Question)

What are the cons about sexual reproduction?

Back (Answer)

• Does rely on a mate - Not as efficient

#13

Front (Question)

In sexual reproduction, the offspring will be _________ from both of its parents.

Back (Answer)

different

#14

Front (Question)

Identical twins result when–

Back (Answer)

One fertilized egg cell splits before growth and development

#15

Front (Question)

Fraternal twins result when–

Back (Answer)

Two egg cells are fertilized by two sperm cells

#16

#17

Front (Question)

What is the female sex cell?

Back (Answer)

Egg

#18

Front (Question)

What is the male sex cell?

Back (Answer)

Sperm

#19

Front (Question)

Why is breeding performed?

Back (Answer)

• Gets desired traits • Maintains a species • Study genetics

#20

Front (Question)

What are Mendel’s rules of inheritance?

Back (Answer)

• Offspring inherit an equal amount of genes from both parents • Two genes for each characteristic • Some genes are dominant over others

#21

Front (Question)

The dominant gene is always expressed by a _______ letter

Back (Answer)

capital

#22

Front (Question)

The recessive gene is always expressed by a _______ letter

Back (Answer)

lowercase

#23

Front (Question)

Who was the first geneticist?

Back (Answer)

Gregor Mendel

#24

Front (Question)

What did Mendel find out?

Back (Answer)

When two heterozygous things are crossed, the ratio of dominant:recessive is close to 3:1
