Document Summary
A population of asexual females can grow twice as fast as population that reproduces sexually. For hermaphrodites, selfin occurs when an individual male gametes fertilize its own female gametes. Selection should favor individuals that can also breed with other individuals (outcrossing) When mates are unavailable individuals self fertilize. Does not produce as many viable offspring, but it is better than nothing. Mixed mating can be in response to a lack of resources in the environment. 10m, maximum number of seeds and survivors. All sorts of variability due to the amount of zinc. Zinc is something plants need to live, do not need a lot but it important to life. Zic does effect the number of offspring produced. But not lots of offspring (just need one individual) Sexual selection allows host to evolve at a rate that counters the rapid evolution of parasites. Host and predators/parasites are engaged in an evolutionary arms race .
