Gray whales and yeast cells do not seem like they have much in common, but their dna molecules use the same coding rules to build protein and direct cell function. this universal genetic code that is shared by all living organisms gives possible support for many of the hypotheses about the origin of life. in this assignment, you will examine genes of several different species and apply this information to the hypotheses discussed in the lesson

In cattle a single gene with two alleles determines fur color the fur can be red white or roan roan fur has both red and white hair which of the following statements is true a the allele for roan fur color is dominant over red and white fur color b the allele for red fur color is dominant over white and roan fur color c the roan and white alleles are expressed independently of the other d the red and white alleles are expressed independently of each other
