5.DF2中的白花植株占37/64,红花植株占27/64(3/4的3次方),可知F1的基因型很可能是 AaBbCc,而且三对基因之间自由组合。A每对基因的遗传均遵循分离定律,A正确。B.根据分析,该植物花色的遗传符合自由组合定律,至少受3对等位基因控制;如果还有第4对或更多基因,都是显性纯合的,B正确。C.在F2中,红花占27/64,其中有1/64的个体( AABBCO)是纯合体,即F2红花中纯合子占1/27,则有26/27的个体是杂合体,C正确。D.由于每对等位基因都至少含有一个显性基因时才开红花,所以F2红花植株中纯合子( AABBCC)基因型只有1种,白花植株中纯合子基因型有23-1=7种,D错误。
