The evolutionary process viewed backward through time, so that allelic diversity is traced back through mutations to ancestral alleles Coalescent theory can be used to make predictions about effective population sizes, ages and frequencies of alleles, selection, rates of mutation, or time to common ancestry of a set of alleles
the union of diverse things into one body or form or group; the growing together of parts
The formation of resinous or polymeric material when water evaporates from an emulsion or a latex system, permitting contact and fusion of adjacent particles; fusing or flowing together of liquid particles

(noun) The act of combining or uniting In ink jet, it usually refers to the recombination of the ink droplets in air before reaching the substrate Frequently a recombination of satellite droplets with the main droplets
Liquid particles in suspension that unite to create particles of a greater volume
The genealogical relations between genes show that all of the extant varieties of a gene must have originated in a single gene; looking from the present to the past, we can say that they descend from a single form to which they coalesce
