Example sentences for: zygotes
How can you use “zygotes” in a sentence? Here are some example sentences to help you improve your vocabulary:
PCS of homologous chromosomes and sister chromatids prior to establishing proper kinetochore-spindle attachment during meiosis I increases the probabilities of both homologues going to the same pole and of equational division of sister chromatids during anaphase I. Upon normal fertilization, MII oocytes with an additional chromosome result in trisomic zygotes; whereas oocytes containing an extra chromatid would be expected to produce 50% trisomic zygotes due to random segregation during anaphase II.
It is known that pronuclear exchange between zygotes does not prevent development of the reconstructed embryos [ 39] but transfer of donor nuclei from later developmental stages into enucleated zygotes brings about restricted development [ 40, 41].
One explanation of this phenomenon is that a factor(s) required for reprogramming of donor nuclei is removed with the pronuclei from recipient zygotes.
This might be because large gametes, yielding well-funded zygotes, are likely to be more strongly selected if the resulting offspring needs to grow into a large and complex organism.
When examining the in vivo effects of HIV-1 Tat protein in the Xenopus embryo, it was found that upon injection of synthetic Tat mRNA into zygotes, a marked delay in gastrulation occurred.
