1. the presence in progeny of combinations of genotypes and perhaps phenotypes, not present in either parent, resulting from crossing-over;
2. in microbial genetics, the inclusion of a chromosomal part or extrachromosomal element of one microbial strain in the chromosome of another; the interchange of chromosomal parts or genes between different microbial strains.
