HERE IS THE ANSWER 
----------------------------------
# According to the given question the gametes in the aaBBcc gene is aBc and aBc, and the gametes in AaBbCc will be ABC, Abc, aBC, and abc.# For calculating the hybrid ratio using Punnett’s square, a 3-trait square is used with 64 boxes. This produces 64 different combinations of the alleles.

# A Phenotypic Ratio of 27 ABC: 9 ABc: 9 AbC: 9 aBC: 3 Abc: 3 aBc: 3 abC: 1 abc is formed and the genotypic ratio is 1:2:1.

# Therefore, the ratio of hybrid for the three genes should be 1/8.--------------------------------------------------------------------------------------------------Hope this was helpful to u !!!! ☺☺☺-------------------------------------------------
