Asexual reproduction advantage: speed
Asexual reproduction advantage: speed
Quick offspring production, rapid colonization of new areas
Parents needed for asexual reproduction
Parents needed for asexual reproduction
Only one parent needed
Asexual reproduction disadvantage: genetic variation
Asexual reproduction disadvantage: genetic variation
No genetic variation - offspring genetically identical
Asexual reproduction: risk if environment changes
Asexual reproduction: risk if environment changes
Entire population affected due to lack of diversity
Sexual reproduction advantage: variation
Sexual reproduction advantage: variation
Genetic diversity & mixing, prevents direct disease inheritance
Sexual reproduction & environmental change
Sexual reproduction & environmental change
Better adapted, leads to natural selection & evolution
