    25 % chance of homozygous dominant of white calf that is red.

    Explanation:

    dominant traits = black and white BBWW

    recessive trait = red and white bbWw

    cross between the heterozygous cows

    bW bw

    bW bbWW bbWw

    bw bbWw bbww

    There will be 25 % chance of homozygous dominant of white calf that is red also.

    when two calves that are white and red and heterozygous for the red and white trait mated they produce a phenotype ratio of 3:1 and genotype ratio of 1:2:1. Out of total progeny in punnet square 75% are red and white calves while 25% are red and but no white colour on the skin.

    It shows one of the allele in white gene is recessive trait.
