Population Genetics Flashcards
what are the four reasons for studying population genetic structures? relating to management and conservation
- demography
- dispersal
- differentiation
- genetic diversity
what are the four reasons or studying population genetic structures? relating to ecology and evolution
- behavior
- mating system
- adaptation
- speciation mechanisms
how are allele distributed and changed in populations?
- mutation
- gen drift
- selection
- gene flow
what are advances in molecular genetics?
- PCR
- DNA sequencing
- development of molecular markers
name some invasive an non-invasive sampling techniques
- whaling
- stranded animals
- dart biopsy
- faeces
- sloughed skin
describe how estimates of prior populations sizes can differ?
comparing current abundance, catch records and rates of increase to long term effective population size based on mtDNA, there is a large disagreement on numbers
what is the basis of population estimates?
- population structure
- mutation rates
- generation length
population differentiation involves what two things?
change in allele frequencies and lineage sorting
what sort of population structures can you find variance?
- individuals within a population
- populations within a group
- groups of populations
name some hybridizations of minke whales
common minke whale
dwarf minke whale
southern minke whale
name two killer whale ecotypes
transient
resident
