Detailed Solution

There are 27 different genotypic combinations for a trihybrid cross.
Crossing pure lines that varied only in one feature constituted Mendel's initial series of tests. A crucial study method is, to begin with, the most straightforward scenario like Mendel did.
A trihybrid cross is created when three qualities are combined. We must do a trihybrid cross to answer the question. The formula used to determine the various gamete combinations created is 2n.
n = 3; 23 = 8. Here, a total of 8 gametes would develop.
Parents: X X X AaBbCc. ABC, ABc, AbC, aBC, Abc, aBc, and abc all developed into gametes.
27:9:9:9:9:3:3:3:1 is the phenotypic ratio. For the given hybrid, there are 8 distinct phenotypes. There are also 27 distinct genotypes.
