heterozygote = has two different alleles for a given gene
homozygote = has two copies of the same allele for a given gene

>take mouse that's heterozygous for a gene you want (one of the alleles is the one you want)
>put it in a cage with a mouse of the opposite sex who isn't (neither of the alleles are the one you want)
>some of their offspring will be heterozygotes and some won't
>do this with another breeding pair
>breed the heterozygote offspring of both pairs together
>some will be homozygotes for that gene (both of their alleles will be the one you want) and some won't
