Question 1

Blending

Answer 1

Hypothesis is the idea that genetic material from the two parents blends together-a pricnicple accounts for the passing of traits from parents to offspring

Question 2

Particulate

Answer 2

Hypothesis is the idea that parents pass on discrete heritable units (genes)

Question 3

Character

Answer 3

Heritable feature that varies among individuals

Question 4

Trait

Answer 4

Each variant for a character

Question 5

True-breeding

Answer 5

Plants that produce offspring the same variety when they self-pollinate

Question 6

Hybridization

Answer 6

Mating two contrasting, true-breeding varieties

Question 7

P generation

Answer 7

True-breeding parents

Question 8

F1 generation

Answer 8

Hybrid offspring of the P generation

Question 9

F2 generation

Answer 9

F1 individuals self-pollinate or cross-pollinate with F1 hybrids

Question 10

Law of segregation

Answer 10

Mendel crossed contrasting, true-breeding white and purple flowered pea plants producing F1 hybrids all purple, crossed F1 hybrids with F2 producing purple an white and discovered a 3:1 ratio in F2 generation

Question 11

Dominant

Answer 11

Purple, presides over recessive, “R”

Question 12

Recessive

Answer 12

White, masked by dominant, “r”

Question 13

Heritable factor

Answer 13

Gene

Question 14

Mendel’s model: First

Answer 14

Mendel developed a hypothesis of the 3:1 ratio inheritance pattern pf F2 offspring

Question 15

Alternative versions

Answer 15

Account for the variations in inherited characters

Question 16

Alleles

Answer 16

Alternative versions of a gene

Question 17

Each gene resides where on a specific chromosome?

Answer 17

Specific locus

Question 18

Mendel’s model: Second

Answer 18

For each character and organism inherits two alleles, one from each parent

Question 19

Dominant allele

Answer 19

Determines the organism’s appearance

Question 20

Recessive allele

Answer 20

No noticeable effect on appearance

Question 21

Law of Segregation

Answer 21

Two alleles for a heritable character separate (segregate) during gamete formation and end up in different gametes

Question 22

What model accounts for the 3:1 ratio observed in the F2 generation?

Answer 22

Law of Segregation

Question 23

Possible combinations of sperm and egg can be shown in what?

Answer 23

Punnet Square
