(A) crcr - homo red crcw - hetero red cwcw - home white (B) CRCR X CWCW (C) (CR)(CR) X (CW)(CW) if you put them into a punnet square and cross multiply you will get your answer to be CRCW a heterozygous red petal flower as red petals are dominant over white and in this case white is recessive so they are dominant from the above information you should be able to answer part D and E yourself! i hope that helped
