您要查找的是不是：
- A polyploid species;a polyploid cell. 一种多倍体物种;多倍体细胞
- Intra gametophytic selfing is characteristic of polyploid species, where as most diploid species reproduce by inter gametophytic mating. 多倍体之蕨类多行同配子体自交，反之，二倍体蕨类之配育则以异配子体交配为主。
- But an important recent discovery is that most taxonomically recognized polyploid species are of multiple origin, instead of mono-origin. 过去认为多倍体只能是进化的死胡同，现在发现很多多倍体类群都是多元起源的而不是单元起源的。
- In contrast to homoploid hybrid species,polyploid species are easily diagnosed because of chromosome number changes associated with genome doubling. 与同倍杂合体物种相比，因为与基因组加倍相关的染色体数目的变化,多倍杂合体物种很容易判断。
- Fully isolated polyploid species may arise in one or two generations, and diploid or homoploid hybrid species may achieve isolation in as few as 60 generations (13). 完全隔离的多倍体物种可能在一两代内出现，而二倍体或者同倍体杂种经过六十代后可能获得隔离（13）。
- This contrasts with Stebbins' estimate of 30 to 35% for flowering plants, which assumes that all polyploid species within a genus are independently derived. 与斯特宾斯估计的有30至35%25的开花植物进行比较,它假定一个种属内的所有多倍体物种内源性独立。
- a polyploid cell; a polyploid species. 多倍体细胞；多倍体物种。
- Because many polyploidy species are themselves multiply derived, Stebbins' estimate is probably closer to the true polyploid speciation rate. 由于许多多倍体物种是自身繁殖衍生，斯特宾斯的估计可能是更接近真正的多倍体物种形成率。
- a polyploid species; a polyploid cell. 一种多倍体物种；多倍体细胞
- In contrast, polyploidy species need not have low fertility during intermediate stages. 其次，基因组的副本可以保护这种新形成多倍体的遗传完整性。
- Do wolves belong to the canine species? 狼是犬科动物吗？
- We should do our best to save endangered species. 我们应该竭尽全力挽救濒于灭绝的生物。
- This rare bird has become an endangered species. 这种珍禽已成为濒临灭绝的物种。
- He was wearing a strange species of hat. 他戴着一种奇怪的帽子。
- There are many species of chrysanthemum. 菊花品种很多。
- Today the survival of our species is threatened. 今天人类的生存受到了威胁。
- The giant panda has become an endangered species. 大熊猫已成了一种濒临灭绝的动物。
- Unlike most other bats, this species is diurnal. 这种蝙蝠与大多数蝙蝠不同，是在日间活动的。
- Niche separation,low dispersal, and selfing increase the probability of successful matings during early stages of polyploid species establishment; 在多倍体物种形成的早期，生态位隔离，低分散以及自交，增加杂交成功的几率；
- This species of flower flourishes in a warm climate. 这种花在温暖的气候中长得茂盛。
