Genetics in conservation Flashcards
molecular markers
provide info on individuals, populations, etc.
genetic markers much be
heritable, have useful level of variation among samples, should be selectively neutral
what are some approaches for looking at genetic markers?
DNA sequencing and PCR (small samples)
what are some genetic markers?
nuclear DNA and mitochondrial DNA
- powerful together
mitochondrial DNA is…
non-recombining and uniparental inheritance
what are microsatellites?
key markers or variable regions
why are SNPs replacing micro satellites?
cheaper and millions in a genome
molecular sexing
use genes that differ between sexes
PID vs PSIB
PID is for unrelated individuals and PSIB is for siblings. If there is a low chance of two being the same, they are probably from the same individual
assignment tests
what population does an organism, belong to?
- useful for poaching
tragedy of the commons
thought that natural resources are common and inexhaustible
