Sexual reproduction (advantages and disadvantages)
Costs of sex (in terms of evolutionary fitness)
Half of all alleles are thrown away during meiosis!
Only daughters can produce eggs, so why have sons?
Unisexual lizard populations grow twice as fast as bisexual populations.
Advantage of sexual recombination
Sexual populations have higher genetic variation than asexual populations.
Higher genetic variation enables sexual populations to adapt to environmental changes.
