Polyandry Case Study
WEEK 5 ANIMAL MATING SYSTEMS
1)
Polyandry is uncommon because female investment in eggs exceeds that of males in sperm
Polyandry increases the genetic diversity of the offspring, rendering the population more resilient overall. This is especially important in eusocial and colonial animals, where higher genetic diversity results in less parasitic and pathogenic infections.
2)
A. There is a positive correlation between harem size and male body length/ female body length in the graph. It can be seen that if seals size get bigger, seals will be more attracted to the seal and therefore have bigger harem size. Bigger male seals can protect their harem from predators and there is a more opportunity to reproduce rapidly.
B. The main prediction could
