A cow with red coat is crossed with a bull having white coat. Their offspring produced in F1 generation showed roan coat. This effect is produced due to juxtaposition of small patches of red and white colour. What can be assumed about the gene controlling coat colour in cattle ?

Question

A cow with red coat is crossed with a bull having white coat. Their offspring produced in F1 generation showed roan coat. This effect is produced due to juxtaposition of small patches of red and white colour. What can be assumed about the gene controlling coat colour in cattle ? (A) The alleles of gene controlling coat colour show a perfect dominant recessive relationship (B) The alleles of gene controlling coat colour are incompletely dominant (C) The alleles of gene controlling coat colour are co dominant (D) None of these
