One type of roan color in horses is fully dominant over normal solid color and results in the presence of white hairs interspersed among the solid color hairs. the locus for one type of paint in horses (overo paint) is fully dominant, but when homozygous the overo allele is lethal. both loci are autosomal. two roan and paint horses that are heterozygous for roan and heterozygous for overo paint were crossed. what is the probability that their first offspring is also a roan and paint horse? consider only living progeny.
