Mendel’s​ ​Laws ● Law​ ​of​ ​Segregation​ ​​ ​(**1​ ​gene**) o Alternative​ ​versions​ ​of​ ​genes​ ​account​ ​for​ ​variations​ ​in​ ​inherited​ ​characters. o For​ ​each​ ​character,​ ​an​ ​organism​ ​inherits​ ​2​ ​alleles​ ​for​ ​a​ ​gene,​ ​one​ ​from​ ​each parent. o If​ ​the​ ​2​ ​alleles​ ​differ,​ ​the​ ​dominant​ ​allele​ ​determines​ ​the​ ​organism’s appearance;​ ​the​ ​recessive​ ​allele​ ​has​ ​no​ ​effect​ ​on​ ​appearance. o Two​ ​alleles​ ​for​ ​a​ ​heritable​ ​character​ ​segregate​ ​during​ ​gamete​ ​formation​ ​and end​ ​up​ ​in​ ​different​ ​gametes. ● Law​ ​of​ ​Independent​ ​Assortment​ ​​ ​(**2​ ​or​ ​more​ ​genes**)o Two​ ​or​ ​more​ ​genes​ ​assort​ ​independently​ ​–​ ​each​ ​pair​ ​of​ ​alleles​ ​segregates independently​ ​of​ ​each​ ​other​ ​pair​ ​of​ ​alleles​ ​during​ ​gamete​ ​formation.
