Question

Many of your heritable traits are ________. (check all that apply)

Answer 1

I would say that many of our heritable traits are influenced by several genes and by the environnement.

It's, for the biggest part, because of the mutations. You have your heritables traits thanks to your mom and your dad. But a mutation caused by either several rays like ultraviolets or chemicals can changed your traits.

Hope this helps !
