Homoplastic mutations
WebPrior to the advent of molecular work, the observable variation in vegetative reproduction has been used to classify Lejeunea into subgenera and sections. Thereby, the ability of developing caducous leaves was regarded as major factor. A reexamination of several Lejeunea specimens revealed that L. cocoes with caducous leaves shows considerable … Web18 nov. 2009 · Stochastic variation in homoplastic mutations and sequencing errors may explain topological differences within the B. mallei clade, which was mostly supported by non-homoplastic characters. Stochastic variation in all three parameters may be sufficient to cause topological differences among B. pseudomallei relationships, ...

Homoplasmy is a term used in genetics to describe a eukaryotic cell whose copies of mitochondrial DNA are all identical. In normal and healthy tissues, all cells are homoplasmic. Homoplasmic mitochondrial DNA copies may be normal or mutated; however, most mutations are heteroplasmic (only occurring … Meer weergeven In almost every species, mitochondrial DNA is maternally inherited.
