Inheritance

Question 1

What are pedigrees?

Answer 1

Graphic representation of how a trait is passed from parents to offspring

Question 2

What is the principal of independent assortment?

Answer 2

Inheritance of one trait has no effect on the inherited of another trait.
ex: your eye colour (trait#1) is inherited separately from your hair colour (trait #2)

Question 3

Traits are determined by what on the chromosomes

Answer 3

Traits are determined by the ‘genes’ on the chromosomes.

Question 4

A gene is a segment of a DNA that determines what?

Answer 4

It determines a trait

Question 5

Homologous pairs- matching genes- one from which each parents?

Answer 5

One from female parent and one from male parent

Question 6

Alleles are what?

Answer 6

Different genes (possibilities) for the same trait ex: blue eyes or brown eyes

Question 7

A gene that prevents the other gene from showing is called

Answer 7

Dominant

Question 8

A gene that does not show even though it’s present is called

Answer 8

Recessive

Question 9

What is homozygous/purebred

Answer 9

Both genes of a pair that are the same

Question 10

If there is one dominant and one recessive it is called

Answer 10

Heterozygous or hybrid

Question 11

What is a genotype

Answer 11

The combination of genes and organism has ( actual Genetic makeup)

Question 12

The physical appearance resulting from gene makeup is called

Answer 12

Phenotype

Question 13

What is the purpose of Punnett square

Answer 13

A top that is used to predict the possible gene makeup of offspring is called a Punnett square

Question 14

What is monohybrid cross

Answer 14

The technique used to calculate Punnett square possibilities

Question 15

Name list of types of gene expression

Answer 15

Complete dominance, incomplete dominance, codominance, sex traits and determination

Question 16

Mouse fur colour and eye colour are examples of

Answer 16

Complete dominance

Question 17

When one allele is not completely dominant over other (they blend) this is called

Answer 17

Incomplete dominance

Question 18

What is codominance

Answer 18

When both alleles are expressed

Question 19

sex linked traits: genes for these traits are ONLY ON the what chromosome (NOT on the Y chromosome)

Answer 19

X chromsome

Question 20

Examples of recessive sex linked disorders are what

Answer 20

Colourblindness

Question 21

N equals what and n equals what for colour blindness

Answer 21

N equals normal vision and n is colour blind

Question 22

What is hemophila

Answer 22

Blood won’t clot

Question 23

What are the 4 blood types

Answer 23

A, B, AB, and O

Question 24

For humans the alleles for blood type are

Answer 24

IA, IB, and I.

Question 25

IA and IB are ?? and I is ??

Answer 25

Dominant and recessive

Question 26

What is the Rh factor

Answer 26

The Rh factor is a protein that produces an Rh antigen on the surface of red blood cells much like the A and B antigens
