Population Genetics Flashcards
polymorphic
allele varient that is present in more than 1 percent of the popluation
highly polymorphic genes determine what
individual charactersitics
nonpolymorphic genes do waht
code for proetins with essential celluarl fucntiosn
every human is expected to carry how many deleterious recessive muations
3
how many nucleotide polymorphisms are between unrelated humans
6 million
what percentage of the world=s polymorphisma re found within any given popluation
90%
idea population has what characteriscs
large popluation size
equal fitness of offspring
random mating
no mutation or migration
genetic drift
small population
why does eugenics not work
the vast majority of mutant alleles are found in heterozygeotes, serving as a large reservoir for the trast
preenting reproduction of heterozygote carriers for recessive diseas will prevent reproduction altoghetr (since we all ahve detrimental alleles)
What does CF protect hyterozygotes agaisnt
typhoid fever
what population is most affected by CF
uropean
what does beta thalassemia protect heterozygotes agaisnt
malaria
what population is most affected by beta thalassemia
mediterranean
what does HFE protect heterozygotes agaisnt
plague
what population is most affected y HFE
european
