Red and White Holsteins
The expression of red colour replacing the black in Holsteins is a function of a recessive gene. Assuming the allele 'B' stands for the dominant black and 'b' for the recessive red, cattle with the paired genes 'BB', 'Bb', or 'bB' would be black and white, while 'bb' cattle would be red and white.

Should touch my hands and let them go.”
