Question

In all three species of phalarope, a taxon of wading shorebirds, the majority of parental care is provided by the male. based on the bateman-trivers hypothesis of sexual selection, what would you expect to see in phalaropes?

Answer 1

I would expect to see HIGHER MALE INVESTMENT.
Bateman Triver hypothesis of sexual selection states that males compete with one other and female are choosy in which male to mate with when it comes to sexual reproduction.
