Answer 1

F1 Generation

Question 2

the organism has 2 identical alleles for a particular trait. (TT or tt; purebred)

Answer 2

homozygous

Question 3

the organism has 2 different alleles for the same trait (Tt; hybrid)

Answer 3

heterozygous

Question 4

factors that control traits

Answer 4

genes

Question 5

passing of traits from parents to their offspring

Answer 5

heredity

Question 6

parental purebred plants. Each plant has the same type of allele

Answer 6

P Generation

Question 7

self pollinated plants that produce offspring that are identical to the parent

Answer 7

Purebred

Question 8

genetic makeup of alleles (1TT: 2Tt:1tt or 1:2:1)

Answer 8

genotypes

Question 9

plants produced by crossing parents with different characteristics

Answer 9

hybrids

Question 10

physical characteristics of the offspring (3 TALL: 1 SHORT or 3:1)

Answer 10

phenotype

Question 11

transfer of pollen from the flower of one plant onto a flower of another plant

Answer 11

cross-pollination

Question 12

some alleles are more noticeable or occur more often (dominant) and some are not noticeable or occur less often (recessive)

Answer 12

dominance

Question 13

different forms of genes

Answer 13

alleles

Question 14

transfer of pollen from male to female flower part to produce seeds

Answer 14

pollination

Question 15

process in which pollen from one flower falls onto a flower of the very same plant

Answer 15

self-pollination

Question 16

characteristics that parents pass to offspring

Answer 16

traits

is only not seen when it’s not with a dominant (tt=short; lowercase letter)

Answer 17

recessive
