能自交的兜是很好的育種材料啊,還是有什麽辦法讓兜自交?作者: 凝胶 时间: 2009-7-14 20:36
这个……又不是考试做选择题,需要选几率最大的的一项,实际情况也可能是小几率事件的,况且叶绿体来自父本的可能性并非非常之低……
简单查了一下资料
参见摘要 The hows and whys of cytoplasmic inheritance in seed plants
HL Mogensen - American Journal of Botany, 1996
Cytoplasmic organelles are inherited in a nonMendelian fashion in all eukaryotic organisms investigated. Among the seed plants, plastics can be inherited strictly from the female parent, strictly from the male parent, or biparentally. Most flowering plants studied to date exhibit maternal plastic inheritance, but approximately one-third of the genera investigated display biparental plastic inheritance to some degree. Among the gymnosperms, paternal plastic inheritance is the rule in the conifers, whereas the other groups appear to have maternal plastic inheritance, although they have been less well studied.
