Question

A population of scrub-jays live on Catalina Island, off the coast of southern California. This year has been a particularly dry with minimal rainfall and limited seed production for the spring. The smaller-sized jays are able to consume enough food and reproduce, whereas the larger jays with higher biomass are unable to collect enough nutrition to mate this year. Body size has been shown to be heritable in this population. This type of ["frequency-dependent", "disruptive", "directional", "stabilizing"] selection will ["increase", "reduce", "maintain"] the variation in the population.

Explanation / Answer

The answer will be frequency distribution selection will reduce the variation in population.it is so as the genotypic and phenotypic variation are present and according to the habitat evolution is necessary .this phenotype shows the phenotype of body size the smaller ones have more nutrition as compared to the bigger one hence it frequency based progeny as tgettwo are compared.and it will decrease variation as the less nutrition supply will extinct the progeny slowly hence decresingdethe population
