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.
