Question

Ruff birds have a behavioural polymorphism in which Independents are aggressive and Satellites sneak copulations. If ruffs are like Onthophagus beetles then we would predict that _________.

Satellites would have larger testes than Independents.

Independents would have small horns.

Satellites would have large horns.

Independents would have larger testes than Satellites.

Satellites would be female and Independents would be male.

a.

Satellites would have larger testes than Independents.

b.

Independents would have small horns.

c.

Satellites would have large horns.

d.

Independents would have larger testes than Satellites.

e.

Satellites would be female and Independents would be male.

Explanation / Answer

The onthothagus beetle show alternative reproductive pactics which means the alternative ways to obtain fertilisation which leads to a broader category of phenotype. So from the given option E will be correct if we talk about russ birds than the fertilize would be female and independent would be males.
