Corn have inner and outer endosperm. Purple outer endosperm is dominant to colorless outer endosperm. Yellow inner endosperm is dominant to white inner endosperm. Inner endosperm color is not seen if outer endosperm color is in the dominant form. Purple outer endosperm gene is suppressed and not expressed when a dominant color suppressor gene is present. R= purple outer endosperm r=colorless outer endosperm Y= yellow inner endosperm y =white inner endosperm C=Dominant color suppressor c=recessive color suppressor What colors are these corn kernels? CcRrYY, ccrrYy, ccRrYy, CcRryy
so overall the problem says that if R is present the colour of inner endosperm is not expressed. and if C is present then the colour of outer endosperm is suppressed. ill explain the first one. then i hope u can solve the rest. CcRrYY. so now YY would give yellow inner endo colour. but u have Rr so purple outer endo colour. so R would not allow inner yellow colour to express. now lets look at Cc. now u have C so it would not let purple colour express. so now u have no colour in the outer or inner endosperm...
