  4. Dark hair =R light hair =r
    lets say the mom (in this example the heterozygous) has the trait of "Rr". the dad has "rr"(use a punnet square! i willl try to show you)

    R r

    r Rr rr

    r Rr rr

    50% probability their offspring will have dark hair, 50 % probability their offspring will have light hair.
