STUDY GUIDE: 4th NINE WEEKS REVIEW

If a pea plant genotype is heterozygous for seed color, with one allele for green and one for yellow, which trait will be shown?

• Dominant

• Recessive

• A blend of both dominant and recessive

• A mutation

During a biology class, Avery, Aiden, and Michael are discussing the significance of fossils. What does the evidence of evolution suggest to us?

• Adaptations are not necessary for survival

• Organisms have evolved from common ancestors

• Organisms reproduce and pass on their traits

• Organisms have not changed over time
