Pedigrees

     Today in class we learned how to interpret and create pedigrees, which are basically a family tree with genetics. We learned how to determine if the pedigree depicted a gene which is Autosomal (normal) or Sex-linked. We do this by determining if the gene appears more in males or if it appears in males and females about equally. We can then look at the parents genotypes (if given) and their offspring to see if the gene is dominant or recessive. We practiced with these for a while, and even did a hard problem to determine within a huge family who the carriers (heterozygous individuals) are.
