LE 1

When every organism of a species has died.

• Evolution

• Extinction

• Natural Selection

• Artificial Selection

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

• To protect itself against prey.

The theory of evolution by natural selection means that what is changing over time?

• Hair color and eye color

• The acquired traits of a population.

• Attractive features.

• The inherited traits of a population.

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

• Because they come from recessive alleles.

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because the trait is an acquired phenotype.

The passing of genetic material from parents to offspring.

• allele

• genotype

• heredity

• phenotype

Different versions (forms) of a gene.

• heredity

• allele

• phenotype

• genotype

The combination of alleles that you inherited from your parents. This is what you genes look like, the letters. ex. Gg

• heredity

• allele

• phenotype

• genotype

The observable traits. This is what you physically look like, or what gene is expressed. ex. Round Yellow

• heredity

• allele

• phenotype

• genotype

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection

• Genetic Variation

• Homeostasis

• Extinction
