Different forms of a gene account for variations in the inherited traits. can someone explain what this means? i'm confused on how this is worded.

it means you have your mom and dads genes to make it easier for ya to understand! you get it now? ♥

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

allowed for the prediction of the properties of missing elements.
