The pronucleus is the first stage in nuclear division during cell division.
其中文释义为：在细胞分裂过程中，pronucleus是核分裂的第一阶段。
During fertilization, the sperm's pronucleus fuses with the egg's pronucleus to form a diploid zygote.
受精时，精子的pronucleus与卵子的pronucleus结合形成二倍体合子。
The pronucleus contains all the genetic material necessary for the development of an organism.
这句话表明：pronucleus包含了发育成生物体所需的全部遗传物质。
In plants, the two pronuclei fuse to create a single nucleus in the zygote.
在植物中，两个pronuclei会融合形成合子中的一个单一核。
The pronucleus is visible under a light microscope during metaphase I of meiosis.
在减数分裂第一期中期，可以在光镜下观察到pronucleus。
The formation of pronuclei marks the beginning of the prophase I in sexual reproduction.
在有性繁殖中，pronuclei的形成标志着前期I的开始。
Scientists study the behavior of pronuclei to understand early stages of embryonic development.
科学家通过研究pronuclei的行为来理解胚胎早期发育阶段。
Genetic abnormalities can sometimes be detected by examining the structure of the pronucleus.
通过检查pronucleus的结构，有时可以检测到遗传异常。
The fusion of pronuclei is a critical step in ensuring proper chromosome segregation.
pronucleus的融合对于确保正确分离染色体至关重要。
In some organisms, the pronuclei may undergo further modifications before the final nuclear fusion occurs.
在某些生物中，pronuclei在最终核融合发生之前可能还会经历进一步的改变。
