[MeltSim] calculating melting curve of mixture of 2 different DNAmolecules

Well yes, that would be logical approach but as in the high resolution melting
analysis of one gene, you should be able do distinct 3 different  
melt.curves (two for two types of homozygous alleles and one for  
heterozygous allele that is, by the way, in a test tube present as a  
mixture of 4 different kind of dsDNA molecules! So I'm wondering is a  
melting curve of mixture of 2 DNAs just a sum of
2 melting curves of each DNA alone?!
