    1/8

    Explanation:

    The following cross is done:

    GGHhmm X GghhMm

    If genes are unlinked they assort independently, and we can analyze one at a time to obtain the proportions in the offspring, and then multiply those probabilities to get the proportion of appearance of the GgHhmm genotype.

    Gene G/g

    P: GG x Gg

    F1: 1/2 GG, 1/2 Gg

    Gene H/h

    P: Hh x hh

    F1: 1/2 Hh, 1/2 hh

    Gene M/m

    P: mm x Mm

    F1: 1/2 Mm, 1/2 mm

    Total proportion of GgHhmm genotype = 1/2 x 1/2 x 1/2 = 1/8
