Hi I'm not sure if this is covered in bio I was just wondering how is that with the same genetic info siblings look different thanks

it is because of the independent assortment of chromosomes in meiosis. both of your parents have 46 chromosomes in their somatic cells, but 23 in each of there gametes. which specific chromosomes in each of these gametes is completely random, making millions different chromosome combinations possible for the one person, within their individual gametes. thus, a single couple can produce 8+ million children and have none of this look the same, theoretically speaking of course

I think it can also be due to environmental influences dyeing the hair, coloured contact lenses, hair style, etc.

Also, it would be good to remember that the environment can influence phenotype to an extent. Not all phenotypes arise purely because of genetic make up.
