In a Pokémon-like species (“Mon”), body color depends on two genes. The product of the P gene converts a colorless precursor into a pink pigment. The product of the M gene transports pigment to the surface. Each gene has a recessive loss-of-function allele (p and m, respectively). Gene M is recessively epistatic to gene P (any mm genotype produces white coloration). What proportion of offspring will have white coloration from the following cross: Ppmm × PpMm (uppercase P lowercase p lowercase m lowercase m crossed with uppercase P lowercase p uppercase M lowercase m)
