So, what are some of the contributors to change those genes? Is it biologically from within or naturally from the out side influences like air, weather etc.? Thanks!
Gene variations in pigmentation are caused by mutations but are selected for based in environmental factors. So if a trait is good it survives or if it’s neutral it survives but if it’s harmful it dies.
Why is skin color blended if you have a black parent and a white parent while other genes like cleft chin cause either a cleft chin or smooth chin and not a partially cleft chin?
Because of co-dominance involving genes responsible for skin color in heterozygotic individuals. Parents (white, black) are homozygous individuals for these genes. Skin color depend on the amount of active enzymes and other compounds. And this is related to the gene polymorphisms.

Thank you for detailing the components and processes involved. Just the level of detail this science-loving layperson loves to absorb!
Could u reply me
Can i change my skin colour?
@@syed.farhan_7 Are you asking me? I am just another layperson commenting on the video; I have no medical or biological expertise or training.
@@syed.farhan_7logically yes,just move from where you live if you want whiter skin move away from the equator and vice versa
My head hurts. I feel like I am in a biochemistry class that I am forced to sit in. LoL. But thank you for sharing your knowledge.

@A Bro, Crispr genome editing can change skin colour???

@@Edruezzi You have a point. But if you part your hair right and wear a hat, maybe nobody will notice.
Great video,
Thank you for the information
You are n excelent teacher.
How many genes control skin color?
The amount doesn't vary, the strength does
