4. In cattle, polled (absence of horns) is dominant over horned and roan is the result of the heterozygous condition of the genes for red and white coat color. (Neither red nor white is dominant so in the heterozygote, both are expressed.) Assume both traits are on separate pairs of autosomes. What proportion of the offspring of a roan heterozygous polled bull and a roan horned cow would be expected to be roan and horned?
