Genetics

Postby kitty_cute » Fri Jan 13, 2006 5:46 pm

Okay Im rubbish at Science noted. So I quit Chemistry and Physics for GCSE and just did my strongest Biology. Noted. Well this unit we're on genetics - Im just not happy with it, I cant get my head round it at all.

Does anyone know anything about it to help me? Im getting the gist of it (it started today) but... it just confuses me at times, with genotypes, and phenotypes, and hetrozygous and the like ><

example - parental genotype - Hbs - where does the b s come from?!
