Evolution

What part represents the percentage of the heterozygotes in a population of the Hardy-Weinberg Equation?

2pq

What is the definition of genotype?

A set of alleles that determine an individual's phenotype

What is a trait in a species that results in it being better suited to survive and reproduce in its environment?

Adaption

The changes in a species that results in its being better suited to its environment are called ?

Adaptions

Natural selection acts upon ?

Alleles that are expressed

The theory of evolution predicts ?

Alleles that improve survival will increase in frequency within a population

Bird wings and insect wings are ?

Analogous traits

Domesticated rats, the variety you can purchase at a pet store, come in a wide range of color and coat patterns. Many of these coat variations are rarely, if ever, seen in nature. Their presence at the pet store is the result of ?

Artificial selection

For centuries, dog breeders have chosen to breed particular dogs to pass on, or even enhance, desirable traits. This is an example of ?

Artificial selection

The Hardy-Weinberg Principle ?

Can help predict genotypic frequencies and can help predict genetic drift

Two populations of similar organisms will be considered separate species when they ?

Can no longer interbreed and produce fertile offspring

What is the process by which species may change over time?

Evolution

Individual organisms within an existing population cannot ?

Evolve

Given that all forelimbs of all vertebrates share the same basic arrangement of bones, forelimbs are said to be ? structures.

Homologous

What part of the Hardy-Weinberg Equation represents the percentage of homozygous recessive individuals in a population?

Q2

Rapid changes in the gene pool of a population are LEAST likely to occur when there is ?

Random mating and a large population

When individuals of two populations can no longer interbreed, the two populations are considered to be ?

Reproductively isolated

Delicious fruit is an adaption in some flowering plants that assists in ?

Seed dispersal

What is considered a disturbing influence on a population that is at Hardy-Weinberg equilibrium?

Small population size, migration, and mutations

The best explanation for very few species of mammals on the Galapagos Islands is ?

The islands were formed by volcanic eruptions on the ocean floor

A gene mutation in a certain flower allows the flower to produce more seeds. The seeds each have the same chance of producing a new plant as do seeds from flowers that do not possess this mutation. It can be expected that ?

The mutated gene will become more common in the next generation of these flowers

What is not a factor in natural selection?

Individuals of a species cannot compete if they are to survive

According to Darwin, the driving force behind Evolution is ?

Natural selection

An individual has his appendix removed, dyes his hair black, and is morbidly obese? What will he pass down to his offspring?

None of these

Natural selection acts directly upon ?

Phenotypes

What is a group of individuals that belong to the same species, live in a defined area, and breed with others in the group?

Population

In biological terms, the organism that is most successful within its population is the one that ?

Produces the most surviving offspring

In the phrase "Survival of the Fittest" the term "Fittest" refers to the organism's ?

Suitability for its environment

Edible fruit is an adaption in some flowering plants that provides an advantage in ?

Widespread dispersal of seeds

What represents the frequency of the dominant allele in the Hardy-Weinberg Equation?
