Question 1

Genetics

Answer 1

Study of heredity

Question 2

Heredity

Answer 2

Transmission of traits from one generation to another

Question 3

Blending Inheritance

Answer 3

Offsprings are a blend of their parents. (Not completely true)

Question 4

Gregor Mendal

Answer 4

Father of modern genetics, studied peas

Question 5

Pea Characteristics

Answer 5

Self-Fertilize, true-breeding= no cross-pollination
Mature in one season = many generations in a short time
Produce large quantities of offsprings->reduce change results

Question 6

Monohybrid cross

Answer 6

2 individuals identical except for one trait

Question 7

P Generation

Answer 7

Parent Generation

Question 8

F1 Generation

Answer 8

First filial Generation

Question 9

F2 Generation

Answer 9

Second filial generation

Question 10

What types of cross did Mendel preform

Answer 10

Recipricol Cross

Question 11

What did Mendal concluded from his experiments

Answer 11

Characteristics have expressed and latent traits

Question 12

Dominant allele

Answer 12

An allele that if present will always be expressed

Question 13

Recessive Allele

Answer 13

Only expressed when no dominant allele is present

Question 14

Heterozygote

Answer 14

2 different alleles

Question 15

Homozygote

Answer 15

2 same alleles

Question 16

Homozygote dominant

Answer 16

2 dominant alleles

Question 17

Homozygote recessive

Answer 17

2 recessive alleles

Question 18

Genotype

Answer 18

genetic composition

Question 19

Phenotype

Answer 19

Physical appearance

Question 20

Law of Dominance

Answer 20

one trait will cancel another in a heterozygote

Question 21

Punnent Square

Answer 21

predicts/visualizes all possible outcomes from a hybridization

Question 22

Law of Segregation

Answer 22

2 alleles for each gene separate randomly, but equally into the 4 gametes

Question 23

Law of independent assortment

Answer 23

Genes do not influence each other while sorting into gametes

Question 24

Dyhybrid cross

Answer 24

2 Identical individuals except for 2 traits

Question 25

Incomplete Dominance

Answer 25

Offspring with blended/intermediate phenotype

Question 26

Codominance

Answer 26

both alleles expressed simultaneously

Question 27

Multiple Alleles

Answer 27

2+ alleles can exist in a population even though individuals only have 2

Question 28

Wild Type

Answer 28

most common phenotype in a population

Question 29

Sex-Linked Traits

Answer 29

traits that are influenced by genes in the sex chromosomes

Question 30

Linkage

Answer 30

genes that are located physically close together on same chromosomes are more likely to be inherited as a pair

Question 31

Epistasis

Answer 31

One gene modifying the expression of another gene
