Draw

Goal: Using venom as an example, show how the gene versions of siblings can be different from each other and from their parents.

Do:

  • Create a model that shows how the offspring could have different combinations of gene versions.

  • Also draw and label the proteins each spider likely has in their cells.

  • Add annotations to explain how each spider offspring received those gene versions and proteins.

Tips:

  • Try to use the following science words in your annotations: proteins, traits, gene versions, heterozygous, homozygous, and sexual reproduction.
