Multi-level selection of mitochondria Flashcards
(3 cards)
1
Q
Hypothesis
A
The accumulation of some mitochondrial defects is therefore an evolutionary process, involving multiple levels of selection.
2
Q
Two-part experiment
A
First they did a computer simulation, then they tested the results of the simulation with real yeast.
3
Q
what have they shown?
A
We have shown that in S. cerevisiae, within-cell selection favors the accumulation of mitochondrial defects (petite mutants), with functional mitochondria being maintained only when among-cell selection is relatively intense.
