Ch. 11

Question 0

Genetics

Answer 0

The scientific study of heredity

Question 1

Inheritance

Answer 1

Things passed on from one generation to the other

Question 2

True breeding

Answer 2

If allowed to self pollinate they would produce off spring identical to themselves

Question 3

Trait

Answer 3

a specific characteristic that varies from one individual to another

Question 4

Hybrid

Answer 4

Result from cross of parents with different traits

Question 5

What is the offspring of the parent called?

Answer 5

F1

Question 6

After they are crossed how many factors are there for each trait?

Answer 6

2

Question 7

When parents transmit information about traits to their offspring

Answer 7

Factor/genes

Question 8

What are the alternative forms of the factors called?

Answer 8

Alleles

Question 9

Where do the two alleles come from?

Answer 9

Mother and father

Question 10

Principle of dominance

Answer 10

Some alleles are dominant and some are recessive

Question 11

Elle’s that will always be present

Answer 11

Dominant

Question 12

Alleles that are not shown when a dominant is present

Answer 12

Recessive

Question 13

Pure homozygous

Answer 13

Two of the same genes (alleles) for a trait

Question 14

Hybrid/heterozygous

Answer 14

Two different alleles for a trait

Question 15

Combination of alleles or genes for a certain trait

Answer 15

Genotype

Question 16

Visible traits

Answer 16

Phenotype

Question 17

Why do recessive phenotype reappear and show?

Answer 17

They were segregated from the dominant allele during the formation of the gametes

Question 18

Law of Segregation

Answer 18

Members of each pair of alleles separate when gametes are formed. A gamete will receive one allele or the other

Question 19

What do alleles together makeup?

Answer 19

Genotypes

Question 20

A method using probability to predict the outcome of the crosses

Answer 20

Punnent square

Question 21

Monohybrid

Answer 21

Crosses that involve one trait

Question 22

Dihybrid

Answer 22

Crosses that involve two traits

Question 23

Law of Independent Assortment

Answer 23

Genes for different traits can segregate independently during the formation of gametes

Question 24

Incomplete dominance

Answer 24

The phenotype of the heterozygote is in between those of the homozygous parents

Question 25

What is an example of incomplete dominance?

Answer 25

Red and white flower=pink flower

Question 26

Co-Dominance

Answer 26

The phenotype of the offspring expresses the phenotype of each parent equally

Question 27

Sex-linked

Answer 27

Traits are controlled by genes located on the sex chromosomes, the sex chromosomes determine whether the baby will be a boy or girl

Question 28

Hemophilia

Answer 28

A blood disease when your blood does not clot easily (make scabs)

Question 29

How many genes are there for color blindness?

Answer 29

3

Question 30

Multiple Alleles

Answer 30

When two or more alleles exist for one gene, each organism can have just two

Question 31

What are some examples of thing with multiple alleles?

Answer 31

1. Eye color 2. Rabbit coat color 3. Human blood type

Question 32

What are the different types of blood types?

Answer 32

1. A 2. B 3. AB 4. O

Question 33

How is O blood written?

Answer 33

II or ii, Ii

Question 34

Polygenic

Answer 34

Traits are produced by the interaction of several genes
