ye color is a fascinating human inherited trait. Genetically eye color is thought to be inherited with two major genes,one that controls for brown or blue and one that controls for green or hazel and others that modify this trait. For our purposes for this exercise we will consider only the genes for brown or blue eyes. Usually, though not invariably, human eye color is inherited as if brown eyes were due to a dominant factor/allele (B) and blue to the corresponding recessive allele (b). Assume that this is correct in the following problems. Use Punnett square and probability formulas to determine your answers. Read the problems carefully to determine what is asked for and what information you already have.
