Inheritance Quiz

Question 1

Who is Gregor Mendel and why is he important?

Answer 1

Gregor Mendel discovered the basic principles of heredity and laid the mathematical foundation of the science of genetics

Question 2

Heredity

Answer 2

Passing traits down from one generation to the next

Question 3

Trait

Answer 3

Distinguishing quiality/characteristic

Question 4

Hybrid

Answer 4

offspring of two plants or animals of different species or varieties

Question 5

Gene

Answer 5

Basic unit of heredity passed from parent to child

Question 6

Allele

Answer 6

alternate form or variations of a gene

Question 7

Dominant

Answer 7

Overpowering gene

Question 8

Recessive

Question 9

Gamete

Answer 9

Reproductive cell of an animal or plant

Question 10

Probability

Answer 10

ex. 50% or 100%

Question 11

Genotype

Answer 11

genetic makeup of an individual

Question 12

Phenotype

Answer 12

the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Question 13

Homozygous

Answer 13

having inherited the same versions (alleles) of a genomic marker from each biological parent.
Homozygous dominant: BB
Homozygous recessive: bb

Question 14

Heterozygous

Answer 14

having two different alleles of a particular gene or genes.
Example: Bb

Question 15

Punnett Square

Answer 15

summary of possible combinations of maternal alleles with paternal alleles

Question 16

Know how to complete punnett squares

Question 17

Incomplete dominance

Answer 17

both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype

Question 18

Codominance

Answer 18

two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.

Question 19

X-linked traits

Answer 19

the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes; males have one X and one Y. Genes on the X chromosome can be recessive or dominant. Their expression in females and males is not the same.

Question 20

Blood Types

Answer 20

A+,A-,AB+,AB-,O

Question 21

Understand pedigrees: how to interpret and create them
