If 25% of carnations in garden are white what percent of carnations in this population is expected to be pink?

(asume the population is in H/W equilibrium)
In Carnations, flower color is determined by a single gene may have either a red allele or a white allele but these alleles exhibit incomplete dominance when they coexist in an organism's genome.
