... Inversions generally do not result in lost DNA, but phenotypes can arise if the breakpoints are in genes or regulatory regions. Linked genes are often inverted together. The meiotic consequence depends on whether the inversion occurs in a homozygote or a heterozygote. – A homozygote will have normal ...

Horizontal Gene Transfer Horizontal gene transfer
... In most cases, the DNA that is transferred from the donor to the recipient consists merely of a copy of the plasmid. However, some types of plasmids can also promote transfer of chromosomal DNA. The first of these to be discovered, and the best known, is the F (fertility) plasmid of E. coli, but sim ...
