microevolution

change in allele freq?

evolution has occured

no change

evolution has occured, in equil.

why does variation persist?

cuz envir changes sm, select diff phenotype

inbreeding?

mating between relatives

fitness consequences

\

inbreeding depression

too many homozygous recessive individuals

prone to death

cant pass traits on

micro evolution

change in genetic makeup of pop from 1 gen to the next

small changes in allele freq

phenotypic plasticity

same genetic makeup, diff environments look diff

flowers watered in soil compared flower never watered in soil

qualitative variations

polymorphisms; distinct traits, either red or blue petals

and its a change in base pair sequence. makes diff alleles

phenotypes

genetic diff

environmental (soil acidity)

only genetic is inherited
