If a horse with red hair (genotype $H^R H^R$) is crossed with a horse with white hair (genotype $H^W H^W$), the young produced show both red and white hair (genotype $H^R H^W$). Such horses are said to have roan-coloured hair. This is an instance of codominance. If two roan-coloured horses are crossed, what is the probability that their offspring will also be roan-coloured?
