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：
- The autotetraploid cultivar had higher yield and better disease resistance than its diploid parent.（该自四倍体品种产量更高，疾病抗性也比其二倍体亲本更好。）
- The autotetraploid population showed more genetic diversity than the diploid population.（自四倍体种群显示出比二倍体种群更多的遗传多样性。）
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
