Flashcards in rate of evolution Deck (8)
what does it mean if the selection pressure is high?
rate of evolution is high
what happens if the rate of evolution is increased?
shorter generation time
sharing of beneficial DNA sequences
what do you need for evolution to occur?
what is selection pressure?
factor in internal or external environment
reduces reproductive success of a population
what is the effect of shorter generation time?
more generations in a set period of time
each cycle requires DNA replication
mutations occur during meiosis and DNA replication
effect of warmer climates
exters selection pressure on all organisms
heat tolerant will have an advantage carry gene on
what is horizontal gene transfer?
sharing of beneficial DNA sequences between sexual reproduction- creates variation
