3
The study of how traits are passed from parent to
child.

• What is genetics?

4
A different form of the same gene.

• What is an allele?

5
The expressed trait (represented by a capital
letter).

• What is the dominant trait (dominant gene)?

6
An organism that has 1 dominant allele and 1
recessive allele.

• What is a heterozygote (heterozygous)?

7
Genotype referred to as being pure.

• What is homozygous?

8
When Mendel crossed a true breeding
purple-flowered plant and a true breeding
white-flowered plant, all of the F1 generation
plants had this color of flower.

• What are purple flowers?

9
The probability that two heterozygous plants for
tallness will produce a short plant.

• What is 25?

10
This law of Mendels states that the genes for
two different characteristics are inherited
separately.

• What is the Law of Independent Assortment?

11
The genotype of a person who does not have a
recessive trait, but one of his/her parents does.

• What is heterozygous?

12
Separation of alleles during the formation of
gametes.

• What is the Law of Segregation?

13
In human blood typing, this allele acts as the
recessive allele.

• What is the O (i) allele?

14
A trait, such as eye or skin color, which is
controlled by two or more genes.

• What is polygenic inheritance?

15
This type of inheritance forms a heterozygote
that displays a blending of the two homozygous
phenotypes.

• What is incomplete dominance?

16
An example of this type of inheritance pattern.

• What is codominance?

17
Human blood type is an example of this type of
inheritance.

• What are multiple alleles?

18
Genotype for males.

• What is XY?

19
Sex chromosome that contains the most genes.

• What is the X chromosome?

20
An individual who do not express a disorder or
trait but can pass the disorder or trait on to
his/her offspring.

• What is a carrier?

21
The probability that a man with hemophilia and a
carrier woman will have a child (of either sex)
with hemophilia.

• What is 50 (½)?

22
The percent chance that a boy will be color blind
if his father is color blind and his mother is
normal sighted.

• What is 0?

23
This type of trait does not show when paired with
a dominant trait.

• What is recessive?

24
Genes are carried on these.

• What are chromosomes?

25
Used to determine the probable outcome(s) of a
cross.

• What is a Punnett Square?

26
Breeding a recessive phenotype with a dominant
phenotype to determine the dominant individuals
genotype.

• What is a test cross?

27
This blood type is the universal recipient.

• What is AB?
