a condition in which neither of two alleles of a gene is dominant or recessive

the likelihood that a particular event will occurIn a genetic cross, the allele that each parent will pass on to it's offspring is based on probability

Genetic makeup, or allele combinations

when an organism has two identical alleles for a trait

An organism's traits are controlled by the alleles it inherits from it's parents. Some alleles are dominant, while other alleles are recessive.

the different forms of a gene for each variation of a trait of an organism

type of cell division where one body cell produces four gametes each containing half the number of chromosomes as a parents body cell

a purebred organism is the offspring of many generations that have the same traiti.e. purebred short pea plants always come from short parent plants

a hybrid organism has two different alleles for a trait

Mendel reasoned that individual factors, or sets of genetic information, must control the inheritance of traits in peas.The factors that control each trait exist in pairs.The female parent contributes one factor, while the male parent contributes the other factor.One factor in a pair can mask, or hide, the other factor.
