Question 0

Trait

Answer 0

Characteristic that is inherited; can be dominant or recessive

Question 1

Heredity

Answer 1

Passing on of characteristics from parent to offspring

Question 2

Genetics

Answer 2

Branch of biology that studies heredity

Question 3

Gametes

Answer 3

Male and female sex cells; sperm and eggs

Question 4

Zygote

Answer 4

Diploid cell formed when a sperm fertilizes an eggs

Question 5

Fertilization

Answer 5

fusion of male and female gametes

Question 6

Pollination

Answer 6

From male reproductive organs to female reproductive organs of plants; usually within the same species

Question 7

Hybrid

Answer 7

Offspring formed by parents having different forms of a trait

Question 8

Allele

Answer 8

Alternative form of a gene for each variation of a trait of an organism

Question 9

Dominant

Answer 9

Observed trait of an organism that makes the recessive form of a trait

Question 10

Recessive

Answer 10

Trait of an organism that can be masked by the dominant form of a trait

Question 11

Law of segregation

Answer 11

Mendelian principle explaining that because each plant has two different alleles, it can produce two different types of gametes. During fertilization, make and female gametes randomly pair to produce four combinations of alleles

Question 12

Phenotype

Answer 12

Outward appearance of an organism; regardless of its genes

Question 13

Genotype

Answer 13

Combination of genes in an organism

Question 14

Homozygous

Answer 14

When there are two identical alleles for a trait

Question 15

Heterozygous

Answer 15

When there are two different alleles for a trait

Question 16
