1. They all can taste it. (They are all heterozygous for the trait ie can taste = C, can't taste = c their phenotype would be Cc. 2. 3 of the offspring ou of 4 would taste it and the other would not. (1 phenotype of CC, 2 of Cc, and 1 of cc.)

If you're crossing BbTt x BbTt, the proportion of bbT_ would be 3/16. When doing a dihybrid cross, 9/16 are dominant for both traits, 3/16 are dominant for one and recessive for the other, 3/16 are the other way around, and 1/16 is...
