Lecture 10: Genomic Conflict (EEB 122)
This lecture analyzes genomic conflict, arising from misaligned interests of genomic elements within cells, organisms, or between individuals. It discusses mechanisms to mitigate such conflicts, like meiotic fairness and uniparental inheritance of cytoplasmic genomes.
Principles of Evolution, Ecology and Behavior (EEB 122)
Genomic conflict arises when the interests of various genomic elements, such as chromosomes and cytoplasmic organelles, are not aligned. These conflicts arise in two situations: either when one unit is contained within another, as a mitochondrion is contained within a cell, or when inheritance is asymmetrical. Genomic conflict can thus occur within a cell, within an organism, or between two organisms, such as a mother and developing fetus. There have been several steps taken to avoid these conflicts in sexual species, including the fairness of meiosis and the uniparental inheritance of cytoplasmic genomes.
