下列何種情況下,來自S1S2植物的花粉可對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.
請幫忙解答一下,謝謝!!!感激不盡!!!

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
