Document Summary

What do genes do: basically, serve as a set of instructions, telling the body what to do, active genes provide codes telling the body to produce specific proteins, these proteins may become body parts, hormones, neurotransmitters, etc. Is like (cid:271)reaki(cid:374)g up (cid:862)gotothegro(cid:272)erystorepi(cid:272)kup(cid:373)ilk(cid:272)o(cid:373)eho(cid:373)e(cid:863) (cid:862)got oth. egro (cid:272)eryst orepi(cid:272)k up(cid:373) ilk.

Insertion of nucleotides becomes (cid:862)pi(cid:272)k up (cid:374)o (cid:373)ilk(cid:863) Some of these changes really do make a difference (coding for different proteins, meaning different instructions) , but sometimes it does not matter and does not make a difference.

Some genes are dominant: and will always display in our phenotype. Some genes are recessive: will only display in our phenotype with 2 copies of the same chromosome for that trait.
