PRESENTATION OUTLINE
alleles-one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
dominant- most important; powerful
genotype-the genetic constitution of an individual organism
heterozygous-a pair of genes where one is dominant and one is recessive
homozygous-a pair of matching alleles
phenotype-the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
punnett square- a grid system that can be set up and used to predict the possible outcomes that may result from the mating process between two individuals, when their genotypes are known
recessive- relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents
