Scheme of the comparison of evolution rates of domains located in multidomain proteins and in separate proteins. r_i^x – evolutionary rates of all instantiations of domain X in human (Arabidopsis) proteins; r_j^y – evolutionary rates of all instantiations of domain Y in human (Arabidopsis) proteins; r_a^x – evolutionary rate of domain X in multidomain protein A; r_a^y – evolutionary rate of domain Y in multidomain protein A; r'_a^x – evolutionary rate of the randomized sequence segment within the boundaries of domain X in multidomain protein A; r'_a^y – evolutionary rate of the randomized sequence segment within the boundaries of domain Y in multidomain protein A.
