When homozygous white cattle are crossed with homozygous red cattle, each of the offspring has a mix of white and red hairs. This blend of colors is called roan. What can you infer about the pattern of inheritance involved in the formation of a roan coat in cattle?

WW x RR = WR, WR, WR and WR

WW = Homozygous white cattle

RR = Homozygous red cattle

WR = Roan (Mix of red and white cattle)

WR x WR = WW, WR, WR and RR

When the roan cattle (WR) is crossed with one another, the offspring produced gives a mix of white and red cattle (75%) and homozygous red cattle (25%).
