下图为细胞融合的简略过程(只考虑两个细胞的融合),若A、B分别是基因型为Hhrr、hhRr两个烟草品种的花粉,且这两对基因分别位于两对同源染色体上,由于一对隐性纯合基因(rr或hh)的作用,在光照强度大于800lx时,都不能生长;下列叙述正确的是

①实验开始时必须用纤维素酶(或果胶酶)除去不利于原生质体融合的物质

②实验中除了杂种细胞外,还有2种细胞

③要想从融合细胞的培养液中分离出基因型为HhRr的杂种细胞,可在大于800lx光照下培养,收集增殖分化的细胞团

④要想从融合细胞的培养液中分离出基因型为hhRr或Hhrr的杂种细胞,可在大于800lx光照下培养,收集增殖分化的细胞团

⑤从理论上分析考虑,将融合细胞的培养液放在大于800lx光照下培养,有5种融合细胞不能增殖分化
