If a heterozygote is crossed with a recessive individual, what % of their offspring will be recessive (have light hair)?

Thank You :)
You are entirely welcome.

Sra (aka Mme)
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.
sorry i guess it didn't come out as planned:(
forget my answer! my bad...
