下列何种情况下,来自S1S2植物的花粉可对S2S3的花成功的完成授粉?
(A)If you used pollen from a carpelate flower,to fertilize a staminate
flower,it would be successful.
(B)If the plants used sporophytic self-incompatibility,half of the pollen
would be successful.
(C)If the plants used gametophytic self-incompatibility,half of the pollen
would be successful.
(D)Pollen from an S1S2 plant can never pollinate an S2S3 flower.
请帮忙解答一下,谢谢!!!感激不尽!!!

2F：推 pcboy0831:In gametophytic self-incompatibility140.112.250.117 11/28 13:33
3F：→ pcboy0831:it depends on the haploid S locus of140.112.250.117 11/28 13:34
4F：→ pcboy0831:the pollen and the diploid S locus of140.112.250.117 11/28 13:34
5F：→ pcboy0831:the stigma ; In sporophytic140.112.250.117 11/28 13:34
6F：→ pcboy0831:self-incompatibility, both S alleles140.112.250.117 11/28 13:35
7F：→ pcboy0831:of the pollen parent are important140.112.250.117 11/28 13:36
8F：→ pcboy0831:So, in (C) , if pollen S1 ==> S2,S3140.112.250.117 11/28 13:37
9F：→ pcboy0831:stigma, it will grow ; but if pollen140.112.250.117 11/28 13:38
10F：→ pcboy0831:S2 ==> S2,S3 stigma, it will not.140.112.250.117 11/28 13:39
11F：→ pcboy0831:because both S2 alleles match140.112.250.117 11/28 13:39
