Mniej wiêcej wygl±da to tak:

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.

Cytat:
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.
