Activator https://www.youtube.com/watch?time_continue=2&v=Hm4BxQen 6SM Based on the evidenced gathered does a change in DNA sequence affect the characteristics (i.e. physical traits) of living things? Please support claim with evidence gathered from the video.

Not all Mutations are Bad Some mutations are beneficial Mutation: permanent change in DNA

Malaria Resistance Hemoglobin mutation called HbS Makes red blood cells take on a curved, sickle-like shape. With one copy, it confers resistance to malaria Two copies, it causes the illness of sickle-cell anemia.

Super Sprinter Gene ACTN3 Controls fast-twitch muscle fibers and flexing 20% of population has mutated gene making them superior athletes

Almond Trees Almond seeds from wild species contain amygdalin (bitter chemical that converts into cyanide inside the human body) A single gene mutation resulted in a variety that no longer synthesizes amygdalin. When humans discovered this non-bitter almond species, they cultivated them, which is continued till today.
