different forms of a particular gene

physical or observable traits an offspring inherits

allele combination an offspring inherits

genotype with two different alleles

genotype with two of the same inherited alleles

allele that hides another trait; only need one allele to display trait

hidden trait; need two alleles to display the trait

father of genetics; worked with pea plants to observe dominant/recessive traits

hereditary pattern where neither allele is dominant and both expressed in offspring

heterozygous genotype is an intermediate phenotype between the dominant and recessive genotypes

an inheritance pattern that is passed on the XX, XY chromosome pairs

More than two alleles are possible for a given trait

tool geneticists use to trace traits through generations

picture (map) of the chromosomes in a nuclei of a cell

when the number of chromosomes is not evenly separated between daughter cells in mitosis or meiosis

Chromosomes pairs 1-22 in humans; any chromosomes that is not a sex chromosome (XX,XY)
