The seed setting rate has no obvious difference between autotriploid and autotetraploid, but it will rise with the increase of the self-bred generations.
③同源三倍体和同源四倍体之间的自交结实率没有明显的区别,结实率会随着自交代数的增加而上升。
“autotetraploid”是一个生物学领域的专业术语,其含义和用法如下:
如需更详细的学术定义或具体案例,可参考生物学词典或相关研究文献。
定义: 自四倍体,指拥有四倍体染色体组的个体或物种。
解释: autotetraploid一般指染色体组中每个染色体的数量是正常二倍,但是这些染色体都是来自同一个物种的,而不是两个不同物种的杂交。
例句:
用法: Autotetraploid通常用于描述植物或动物个体或物种的染色体数量。它可以与其他倍数的形态相对比,如二倍体(diploid)、三倍体(triploid)和四倍体(tetraploid)。
近义词: tetraploid
反义词: diploid, triploid
