Examples: • The degree of similarity between regions of amino acids can tell us how well that region is conserved, which can provide clues about the structural or functional significance of that region. • The DNA sequence alignment of m...

What is linkage disequilibrium? The opposite of linkage equilibrium! Recall Mendel’s 2nd Law: Allels of different genes are passed on independently. When this law holds, there is no correlation between polymorphisms. In this state of random assortment, they are said to be in linkage equilibrium. However, if there are correlated, then they are in linkage disequilibrium. This is the non-random as...
