Lesson details
Lesson outcome
I can explain how sexual and asexual reproduction affect variation and evolution within populations of organisms.
Show transcript
Sexual reproduction creates genetic variation in offspring by combining alleles from male and female gametes.
Sexual reproduction occurs at a slower rate than asexual reproduction but creates variation which can lead to evolution.
Asexual reproduction creates genetically identical offspring with no genetic variation.
Asexual reproduction typically occurs at a much faster rate than sexual reproduction.
Organisms that reproduce asexually can evolve if the environment or DNA copying errors cause changes in their genome.
