0 a cell formed by the union of a male and female gamete -- zygota
The zygote later develops into an embryo.
Most zygote isolations were completed using cellulase and pectinase because the enzymes substantially improved this process.
In five zygotes development was delayed and altered.
Here we experimentally enlarged blastomeres to zygote size by enucleation and fusion with blastomeres that were in developmental synchrony with the recipient.
In these models, inbreeding depression is assumed to affect zygote-to-adult viability only.
The survival of a zygote was determined by generating a random number and comparing it with the relative viability value of the zygote.
Only in about 5% of zygotes evaluated were we unable to detect replicating nuclei at all.
In practice, zygote frequencies cannot be observed directly.
The study forms part of a broader investigation aimed at developing alternative ways of producing human zygotes in vitro.
