Traits and Reproduction

What 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.

What do gene versions do?

• Make the proteins
• Provide instructions for proteins
• Give the  organism its genes
• Pass on the genes to the offspring

How 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.

How 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.

What 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.

 Why 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.

How 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

How many proteins do homozygous genes create?

• They are different
• One protein
• Two proteins
• Three proteins

How 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.
