Darwin observed that most organisms produce more than one or two offspring. This observation led directly to his hypothesis that individuals within a population compete for limited resources.
True
False
A farmer is looking to grow corn with only yellow kernels. He chooses plants with this phenotype and crosses them to produce offspring with the parental phenotype. Over the course of several generations the vast majority of corn have only yellow kernels. This represents an example of natural selection because this trait was chosen for and passed to offspring
True
False
Individuals can be acted on by natural selection, but only populations evolve
True
False
Natural selection acts on genotypes
True
False
Differences observed between males and females of the same species are most directly the result of natural selection
True
False
A species of birds, known scientifically as Cyanocitta cristata, eat the acorns of oak trees. C. cristata will find acorns from a variety of locations and bring them back to their nesting location, which can be a mile or further from the original location of the acorn. The bird does not eat all of the acorns, however. C. cristata may harvest some of the nuts by burying them in soil. These buried acorns can germinate under the right conditions. What mechanism of evolutionary change does this example best represent?
Mutations
Bottleneck effect
Founder Effect
Gene Flow
Natural Selection
Mealworms are not actually worms at all! They are simply the larval stage of the mealworm beetle, scientifically known as Tenebrio molitor. T. molitor serves as a primary food source to many birds, such as Bluebirds. The larger the larvae, the more likely a Bluebird will spot and eat it. This serves as a selective pressure to the mealworm larvae population. What mode of selection does this example best represent?
Directional
Stabilizing
Disruptive
Dimorphic
A prolonged drought that lasted from 2017 to 2019 caused a reduction to the water level of a local lake. The lake serves as the habitat for a population of trout. Due to the reduced water levels, the trout were pushed closer to the surface of the water. This thereby allows birds, like bald eagles, to spot and grab the trout. A heavy rain season in 2020 brought the water levels of the lake back to normal, or pre-2017 levels. The population of trout, however, was significantly reduced. What does this example best represent?
Mutations
Bottleneck effect
Founder effect
Gene Flow
Natural Selection
Mutations can fall into three classes:
(a)
In his book On the Origin of Species, Darwin proposed a logical mechanism for evolutionary change, which he termed (a) . This represented his definition for evolution.
A fire wipes out a significant portion of a specific tarantula population living in South America. This population had two color varieties, solid (dominant) and striped (recessive). After the fire, the only surviving individuals all have striped coloring. The allele for striped coloring in this populations is considered to be (a) .
List the five conditions that must be met for a population to be in Hardy-Weinberg equilibrium
