Assume that the trihybrid cross MM SS tt X mm ss TT is made in a plant species in which M and S are dominant but there is no dominance between T and t. Consider the F2 progeny from this cross, and assume Independent assortment.
- How many phenotypic classes are expected?
- What is the probability of genotype MM SS tt?
- What proportion would be expected to be homozygous for all genes?
