Cytat:
Such a partially diploid cell is termed merodiploid.

Cytat:
The chromosome containing the duplicated region is called a merodiploid or partial diploid; it is highly unstable and tends to recombine back to its original configuration.

merodiploid: partial diploid

Cytat:

Merodiploid
A partially diploid bacterium, carrying both its own chromosome and a chromosome fragment introduced by conjugation, transformation or transduction.

Cytat:
In Hfr x F- matings, the 5' leading strand starts at a nick in the DNA at the replication origin of the F element. Part of the F factor first moves into the recipient cell where it is copied. The attached bacterial chromosome also begins to be transferred to the recipient. Depending on the position of the replication origin at the time of integration, this usually means that only some of the F element is transferred as the remainder of the F element is at the other end of the bacterial chromosome. For all of the F element to be transferred, the entire bacterial chromosome would have to be transferred as well. This happens only rarely as transfer normally breaks before completion. Therefore the recipient usually remains F-, but is diploid for some of its genome. This organism is known as a partial diploid, merodiploid or merozygote.

Cytat:
merodiploid/merozygote: a partially diploid bacterial zygote containing an exogenotic chromosomal fragment donated by the F+ mate; the exogenote may also be introduced during transduction or sexduction

Cytat:
Merodiploid. A bacterium that is only partially diploid--that is, diploid with respect to only some of its genes.
