Detailed explanation-1: -Why does the ability to lay 1, 000 to 5, 000 eggs increase the fitness of the species L. clamitans clamitans? A. It increases the probability that some offspring will survive long enough to reproduce.
Detailed explanation-2: -Graph 1 shows directional selection, in which a single extreme phenotype is favored. Graph 2 depicts stabilizing selection, where the intermediate phenotype is favored over the extreme traits. Graph 3 shows disruptive selection, in which the extreme phenotypes are favored over the intermediate.
Detailed explanation-3: -Disruptive selection occurs when both extreme traits are favored in an environment. Disruptive selection increases genetic and phenotypic diversity in a population, since more than one phenotype, or physical trait, is favored.
Detailed explanation-4: -There are three broad categories: positive directional selection, balancing selection, and purifying selection.
