- TL;DR Summary
- In pairs of alleles subject to the dominant/recessive distinction, can one determine a priori which one will be dominant?
Suppose you have two new alleles whose combination (gene) determine a certain trait, but the trait associated with only one of the alleles (i.e., those which can be compared as dominant/recessive). Of course the classic way, going back to Mendel, was to mix them and see what came out (statistically). But assuming one can sequence each allele before they are mixed (we are assuming that we don't know the outcome), can one, only by looking at the two sequences, determine which one will be determinant relative to the other? (As is certainly clear from my question, I am not a biologist, so the question is on a layman level.)
