The figure below shows data on the survivorship of the salamander Eurycea wilderae. What type of survivorship does this represent?  

A population of caterpillars has skin coloration that is codominant. In this case, there are three distinct color phenotypes: red (homozygous dominant), yellow (homozygous recessive), and orange (heterozygote). All three of these phenotypes are inherited. Birds preferentially feed on these orange caterpillars. The caterpillars also face pressures from parasitic wasps, which lay their eggs inside of their bodies! This is obviously harmful, but the orange orange caterpillars have the ability to defend themselves against parasitic wasps by encapsulating wasp eggs so they will not develop. Thus, the orange phenotype results in some cost, but persists within the population for multiple reasons. This most closely relates to which concept that we learned about in class?

The following plot shows the proportion of male geckos born to different family groups based on rearing temperature. This shows that unlike other gecko traits that are plastic, sex ratio shows very little plasticity.
