- 1. Multiple ChoiceWhat is a mutation and how does it affect genes?A mutation is a growth on an organism.A mutation is a copy of a gene.A mutation is a change in an organisms genes.A mutation is a feature of an organism.
- 2. Multiple ChoiceWhat do gene versions do?Make the proteinsProvide instructions for proteinsGive the organism its genesPass on the genes to the offspring
- 3. Multiple ChoiceHow do different protein structures in cells determine traits?Different protein structures affect how they connect to other proteins molecules.Different protein structures have no effect on connecting genes.Different protein structures can change the gene.Different protein structures provide instructions.
- 4. Multiple ChoiceHow many proteins do heterozygous gene versions create?One proteinTwo proteinsThree proteinsThey are the same.
- 5. Multiple ChoiceHow do organisms get their traits?They get thier traits from their environment.They inherit one copy of a gene from their mother.They inherit copy of a gene version from their mother and father.They get their traits from the proteins they eat.
- 6. Multiple ChoiceWhat does homozygous mean?Two copies of a gene version that are different.Two copies of a gene version that are the same.Two copies of a gene that are mutated.Two copies of a gene that are used to create another gene.
- 7. Multiple ChoiceWhy do siblings and parents different from each other?Siblings get different amounts of genes from their mother or father making them different.Each sibling has a mutation that causes them to have different traits.Siblings use their environment and experiences to determine their traits.Offspring inherit different combinations of gene versions from parents.
- 8. Multiple ChoiceHow do gene versions determine different traits?An organism has two copies of a gene for each feature.Each parent randomly passes on one of its two copies of genes to its offspring.Each gene version provides a unique instruction to make a specific protein molecule in an organism's cells.Traits vary between parents and offspring and among siblings
- 9. Multiple ChoiceHow many proteins do homozygous genes create?They are differentOne proteinTwo proteinsThree proteins
- 10. Multiple ChoiceHow does sexual reproduction result in a variation among offspring?Organisms usually inherit their traits from the parent that lives in the same environment.Each gene version provides a unique set of instructions to make a protein.Protein molecules interact with other protein molecules.Each parent randomly passes on one of its two copes of each gene to its offspring.
- 11. Multiple ChoiceHow do the proteins determine traits in organisms?They give instructions to the genesIt depends on how they connect with other proteinsThe trait depends on what environment the organism lives in.The organism inherits its genes through sexual reproduction.
- 12. Multiple ChoiceWhat does heterozygous gene versions mean?The two copies of a gene for each feature can be the different versions.The two copies of a gene for a feature can be the same version.The two copies of a gene are used for an organisms feature.The two copies of a gene provide instructions for one protein.
