1

Trait

Characteristic that is inherited

2

Genetics

The study of heredity

3

Gamete

Male and female sex cells; sperm and eggs

4

Fertilization

male and female gametes coming together

5

Zygote

diploid cell formed when a sperm fertilizes an egg

6

Pollination

From male reproductive organs to female reproductive organs of plants

7

Hybrid

Offspring formed by parents having different forms of a trait

8

Allele

forms of a gene for each variation of a trait

9

Law of segregation

Mendelian principle explaining that each plant has 2 different alleles and male and female gametes pair to produce four combinations of alleles

10

Phenotype

physical appearance of an organism

11

Heredity

Passing on of characteristics from parents to offspring

12

Law of independent assortment

Principle founded by Mendel stating that genes for different traits are inherited independently of each other

16

Genotype

genetic code represented by two letters which are the alleles

17

what is the rule of unit factors

alleles and genes both determine traits of an organism

18

rule of dominance

dominant is observed, recessive is masked
