trait

variation of a particular inherited character

genetics

study of heredity

cross-fertilization

process by which sperm from one flower's pollen fertilizes the eggs in a flower of a different plant

Hybrid

offspring of two different true-breeding varieties

monohybrid cross

mating of two organisms that differ in only one character

allele

alternative form of a gene

homozygous

having identical alleles for a gene E.x. blue eyd blue eyed

heterozygous

having different alleles for a gene
E.x. blue eyed and green eyed gene

dominant

the allele that shows up in the first generation

recessive

the allele that shows up in the second generation

Punnett Square

diagram showing the probabilities of the possible outcomes of a genetic cross calculated in a box set up

phenotype

type of genes you see

genotype

type of genes you have

testcross

mating of an individual of unknown genotype but dominant phenotype with a homozygous recessive individual

dihybrid cross

mating of two organisms that differ in two characters

intermediate inheritance

inheritance in which heterozygotes have a phenotype intermediate between the phenotypes of the two homozygotes

independent events

an event where the result of the first event effects the second (mulitply)

mutally exclusive

is an event where the result of the first event doesn't effect the second

locus

location of a chromosome where you find a given gene

incomplete dominance

not completely dominant over the recessive gene

codominance

two dominant gene (red times white = pink)

agglutinins

antibodies

sex-linked trait

a trait that is located on the x choromosome

polygenic inheritance

combined effect of two or more genes on a single character

chromosome theory of inheritance

generalization that genes are located on chromosomes and that the behavior of chromosomes during meiosis and fertilization accounts for inheritance patterns

gene linkage

tendency for alleles of genes on the same chromosome to be inherited together

sex-linked gene

gene located on a sex chromosome
