phenotype- what an organism looks like as a consequence of it's genotype. Two
organisms with the same phenotype can have different genotypes.
dominant- a genetic trait is considered dominant if it is expressed in a person who
has only one copy of that gene.
recessive- of genes: producing it's characteristic phenotype only when its allele
is identical.
allele- one of two alternate forms of a gene that can have the same locus on
homologous chromosomes and are responsible for alternative traits. Some
alleles are dominate over others.
