Dominant

refers to the relationship between two versions of a gene. If the alleles of a gene are different, the one allele that is expressed is the dominant allele

genetics

the scientific study of heredity

genotype

the genetic makeup of an organism

heterozygous

Having two different alleles for a particular gene

homozygous

having two identical alleles for a particular gene

phenotype

the physical characteristics of an organism

probability

the likelihood that particular event will occur

Punnett square

a diagram that can be used to predict the genotype and phenotype combinations of a genetic cross

recessive

refers to the relationship between two version of a gene. if the alleles of a gene are different, the one allele that is not expressed if the recessive allele
