That could explain why parthenogenesis reproduction has emerged in so many species.───这就可以解释为什么这么多物种都会有孤雌生殖现象。

Parthenogenesis is so far known to occur in about 70 reptile species.───迄今已知大约70种爬行动物有单性繁殖行为。
In the type of parthenogenesis observed in sharks, one of those cells behaves like a sperm and fertilizes the egg.───鲨鱼在单性繁殖时,这些细胞中的一个起到精子作用为卵子授精。
Another form of apomixis in which seeds develop from unfertilized gametes can also be termed parthenogenesis.───在另一种无融合生殖中,种子从未受精的配子中发育而来,这被称为孤雌生殖。
By a last-resort evolutionary adaptation, female sharks, it turns out, are capable of parthenogenesis, or virgin births.───凭这招进化适应性的杀手锏,雌性鲨鱼原来可以单性生殖,或者说,以童贞女之身怀孕生产。
female parthenogenesis in which the embryo contains only maternal chromosomes due to the failure of the sperm to fuse with the egg nucleus.───由于在精子与卵子融合过程中发生失败而使胚胎只包含母染色体的一种单性生殖。
Whether parthenogenesis is an evolutionary aberration or viable strategy remains debated.───不论这种孤雌生殖方式到底是进化中的歧途还是一种存在争议的策略。
as the material for parthenogenesis nurture, and their offspring for molecular marker identification.───作为材料进行孤雌生殖培育,并对其后代进行分子标记鉴定。
Anyway, Loeb found that, with such simulation, parthenogenesis proceeded.
The nucleotide sequence data of parthenogenesis bacteria will appear in Genbank under the following accession numbers.
This suggests a monophyletic origin for Trichogramma parthenogenesis bacteria.
FIG. 2 A most parsimonious phylogenetic tree of parthenogenesis and cytoplasmic incompatibility microorganisms based on 16S rDNA sequences.
In mammals, however, parthenogenesis seems to be a non-starter.
Parthenogenesis, or something, though neither of us was exactly virginal.
To trigger parthenogenesis, then, Loeb had to simulate fertilisation.
As Pateman notes, parthenogenesis would seem to be the only possibility.
Parthenogenesis is rare among vertebrates but by no means unknown.
