Gregor Mendel
Austrain monk;father of genetics
Self-fertilization
male and female gametes at the same flower combine
Genetics
science of heredity or inherited traits
true-breeding
organism that produce the same traits generation after generation
cross-pollination
crossing gametes of different true-breeding organisms (pea plants)
F1 generation
offspring of the p-cross
F2 generation
the offspring of F1 cross
allele
different from 1 gene
dominant
the trait that apears
recessive
the trait that is masked
p-gerneration
parent gerneration
homozygous

heterozygous
2 differnet alleles for 1 traits
genotype
the pairs of alleles for 1 trait
phenotype
expression of the allele pair; APPEARANCE
law of segregation
alleles separate during meiosis
hybrids
heterozgous organism
genotype ratio
ratio of different genotypes
phenotype ratio
ratio of different phenotypes
