Answer:
27 genotypes; 8 phenotypes
Explanation:
1. Trihybrid cross contain three genes
as given; parents are hybrid for all the traits;
and one allele is dominant over other allele
So, take three genes named Aa, Bb and Cc; assume i) allele A is dominant over a, ii) allele B is dominant over b and iii) allele C is dominant over c.
2. Heterozygous parents are: AaBbCc and AaBbCc
there cross produce offspring like; AABBCC, AABBCc, AABbCC, AABbCc, AaBBCC, AaBBCc, AaBbCC, AaBbCc, aaBBCC, aaBBcc, etc
3. So the total phenotype are 8 phenotypes, because dominant allele show their effect in heterozygous condition too.
4.Total genotypes are 27 genotypes;
