... or nearly identical to their parent. This genetic similarity can be beneficial if the genotype is well suited to a stable environment, but disadvantageous if the environment is changing. For example, if a new predator or pathogen appears and a genotype is particularly defenseless against it, an asexual line...

...enetically close have a higher degree of sequence similarity than organisms that are phylogenetically distant. For example, neutral human DNA sequences are approximately 1.2% divergent (based on substitutions) from those of their nearest genetic relative, the chimpanzee , 1.6% from gorillas [4] , and 6.6% ...

...y did so multiple times, in which case their close similarity to each other is difficult to explain. The size of both organelles is comparable to bacteria. These organelle's ribosomes are like those found in bacteria (70s). Related articles Symbiogenesis Evolution of flagella (Discusses the end...

Cytoskeleton
