Biology 1001A Lecture Notes - Lecture 17: Genomic Imprinting, Parental Investment, Chloroplast
Document Summary
Some con icts arise from uniparental transmission: different genomes= transmitted in different ways, nuclear genes inherited bi-parentally (copy from each of the parents, mtdna (mitochondrial dna) inherited maternally - only mother"s mitochondrial dna inherited, plants: chloroplast mostly inherited maternally. Answer: shutdown male function, reproduce entirely as female. **species of plants with polymorphisms - male and female owers produced some species male sterile - all parental investment to female owers (mutation: cpdna sometimes inherited maternally, sometimes paternally. Perhaps the most interesting thing to come out of the realization of possible con ict within the genome is a philosophical one. We see that we are not even in principle the consistent wholes that some schools of philosophy would have us be. Perhaps this is some comfort when we face agonizing decisions, when we cannot make sense of the decisions we do make, when the bitterness of a civil war seems to be breaking out in our inmost heart.
