Trait
the study of heredity and the variation of inherited characteristics.
genetics
the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote.
fertilazation
an animal bred from parents of the same breed or variety.
purebred
a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
gene
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
alleles
an allele that produces the same phenotype whether its paired allele is identical or different
dominant allele
an allele that produces its characteristic phenotype only when its paired allele is identical
recessive allele
the offspring of two plants or animals of different species or varieties, such as a mule (a hybrid of a donkey and a horse)
hybrid
the extent to which something is probable; the likelihood of something happening or being the case.
probability
diagram that is used to predict an outcome of a particular cross or breeding experiment.
punnett square
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
phenotype
the genetic constitution of an individual organism.
genotype
having each of you alleles the same
homozygus
means having one each of two different alleles.
heterozygus
A condition in which both alleles of a gene pair in a heterozygote are fully expressed, with neither one being dominant or recessive to the other.
codominance
