Biparental inheritance chloroplast
WebMar 19, 2024 · It is believed that biparental inheritance promotes competition between the cytoplasmic organelles and allows the spread of so-called selfish cytoplasmic elements. Those can be, for example, fast-replicating or aggressive chloroplasts (plastids) that are incompatible with the hybrid nuclear genome and therefore maladaptive. WebDec 23, 2004 · Although these studies suggest that maternal inheritance predominates, the small sample sizes used do not allow us to assess whether some paternal or biparental chloroplast inheritance occurs ( Birky 1995; Milligan 1992 ).
