0 the cell that is formed when a female reproductive cell and a male reproductive cell join --
1 the cell that will develop into a baby person or animal and that is created when a male and female gamete (= cell from each parent) unite --
Independently of the number of pronuclei found, -tubulins were uniformly distributed throughout the cytoplasm of the abnormal zygotes.
The transformation of a zygote into an embryo adheres both to nature and to nurture: not only genetics but also environment determines the outcome.
One or two minutes after the last exocytotic events the ridges disappear and the surface of the zygote becomes smooth.
In sharp contrast, human dignity understood as human equality is perhaps too strong insofar as it would include human zygotes and blastocysts.
These injections interfere with the normal process of chromatin decondensation/recondensation occurring in the zygote after fertilisation.
The bright spot at the top of the zygote corresponds to injury at the injection site.
During early events of embryonic development, activated zygotes were compared to in vitro fertilized ones.
The study forms part of a broader investigation aimed at developing alternative ways of producing human zygotes in vitro.
