In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

These two hands-on activities engage students in exploring the genetic basis of cancer using cards and posters.

This tutorial describes how animals differ in their abilities to heal wounds and regenerate lost body parts or damaged tissues.

This animation shows how meiosis, the form of cell division unique to egg and sperm production, can give rise to sperm that carry either an X or a Y chromosome.
