Evolution Intro/Mutation/Non Random Mating

Multiple Choice

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Multiple Choice

A theory has significant evidence to support it.  True or False

• True
• False

Multiple Choice

Which statement best describes Natural selection?

• The best adapted organisms survive and reproduce.

• There are a set amount of organisms.

• Organisms only change through genetic engineering.

• Organisms slowly adapt to their surroundings over a lifetime.

Multiple Choice

Genes that are beneficial to the species will....

• evolve a new species

• will not be passed down to its' offspring

• become more common over time

• cause the extinction of a species

Multiple Choice

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Multiple Choice

an inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.

• adaptation

• natural selection

• niche

• competition

Multiple Choice

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Multiple Choice

Adaptations can be:

• camouflage

• ability to survive cold weather

• hunting skills

• all of the above

Multiple Choice

What is the main purpose of mutations caused by environmental factors?

• To increase genetic stability

• To eliminate genetic variations

• To promote species extinction

• To introduce new genetic traits

Multiple Choice

What is genetic recombination?

• The combination of genes produced by crossing over and independent assortment.

• When genes located close to each other on the same chromosome tend to travel together during meiosis.

• A map that shows the sequence of genes on a chromosome.

• The occurrence of one or more extra sets of chromosomes.

Multiple Choice

Why is genetic recombination a good thing?

• Gives us new genes

• is lethal in humans

• increases genetic variation

• separates during crossing over

Multiple Choice

Which process is responsible for creating new genetic combinations during meiosis?

• Transcription

• Translation

• Crossing over

• DNA replication

Multiple Choice

Which process is responsible for the formation of gametes?

• Mitosis

• Meiosis

• DNA replication

• Transcription

Multiple Choice

What is the main source of genetic variation in a population?

• Genetic drift

• Gene flow

• Natural selection

• Mutation

Multiple Choice

The female birds of paradise tend to look for the most colorful, best dancing males to make babies together.

• Genetic Drift

• Non-random mating

• Gene flow

• Mutation

Multiple Choice

Males of the bighorn sheep species fight one another to show females who is the dominant male and are more likely to mate with females.

• Natural Selection

• Mutation

• Genetic Drift

• Non-Random Mating

Multiple Choice

Yellow toucan birds seek out one another to make babies together and tend to avoid the green toucan birds.

• Genetic Drift
• Non-random mating
• Gene flow
• Mutation
