inherited trait a trait that a person gets from a parent or grandparent
acquired trait characteristics that are gained by an organism after birth as a result of external influences or its own activities that change its structure or function and cannot be inherited
trait a distinguishing quality or characteristic, typically one belonging to a person.

cell the smallest structural and functional unit of an organism
clone an organism or cell, or group of organisms or cells, produced asexually from one ancestor or stock, to which they are genetically identical
mutation the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations
sexual reproduction the production of new living organisms by combining genetic information from two individuals of different types (sexes)
allele 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, or influential
recessive relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents
homozygous if you're homozygous, you've got a pair of matching alleles, which are the two genes that control a particular trait
heterozygous the genetics term heterozygous refers to a pair of genes where one is dominant and one is recessive — they're different
phenotype the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
Punnett square a diagram that is used to predict an outcome of a particular cross or breeding experiment
