1

inheritance

genetic material received from parents

2

probability

likelihood (chance) an event might occur

3

What is the equation for probability?

# of ways a specific outcome can happen divided by # of total outcomes

4

meiosis (my-O-sis)

cell division that produces gametes (reproductive cells)

5

diploid (DIP-loid)

cells that contain pairs of chromosomes (one from each parent)

6

haploid (HAP-loid)

cells that contain only ONE chromosome from a matching pair (this occurs only in reproductive cells)

7

genotype (GENE-o-type)

genetic plan the combination of alleles (the "type-o-genes" an organism has)

8

phenotype (FEEN-o-type)

the traits, or characteristics of an organism (the expression of genetic info)

9

heterozygous (het-er-oh-ZY-gus)

inheriting two differing forms of a particular gene (Example: Tt)

10

homozygous (hom-oh-ZY-gus)

inheriting two identical forms of a particular gene (Example: TT or tt)

11

dominant trait

covers up or masks other forms of the gene

12

recessive trait

gets covered up by other (dominant) forms of the gene

13

carrier

an individual that has a recessive trait but does not show it

14

pedigree

a tool that follows the occurence of a particular trait in a family

15

sex-linked traits

traits that are controlled by genes on the X or Y chromosome

16

allele

a specific form of a gene

17

genetic material received from parents

inheritance

18
