the different forms of a gene

a chart that shows all the possible combinations of alleles that can result from a genetic cross

an allele that is masked when a dominant allele is present

having 2 different alleles for a trait

A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents

an organism's physical appearance or visible traits

the process that occurs in the formation of sex cells by which the number of chromosomes is reduced by half

a characteristic that an organism can pass onto its offspring through its genes

A reproductive process that involves only one parent and produces offspring that are identical to the parent.
