Document Summary
Utensilus plasticus feeds on small prey items, especially marshmallows. The population consists of two different head shapes, forks (n = 16) and spoons (n = 4). There is a sudden change in the prey population because an invasive species, the lima bean (hard, oval), is now present in a higher number than the typical prey species, the marshmallow. Lecture 4 presented this scenario, asked what hypotheses and predictions would you propose (a) correct, as morphology (head shape) and environment (prey) now both play a role in reproductive success. Week 1 lo-2, week 2 lo-1. Which of the above observations provides the best example of phenotypic variation: observation (i, observation (ii, observation (iii, observation (iv, observation (v) Which of the above observations is an example of sexual dimorphism: observation (i, observation (ii, observation (iii, observation (iv, observation (v) (c) correct, sexual dimorphism refers to different phenotypes in males vs. females of same species.
