Zygote

the cell produced by the union of two gametes, before it undergoes cleavage.
historical examples

if this is true, the centrosome of the zygote nucleus must be entirely derived from that of the male pr-nucleus.

from such a cell (zygote), half male, half female, the body of every living organism has sprung.

but if the basis is not there, no amount of education can transform that zygote into a mathematician.

the first change the zygote undergoes in all animals is what is generally called the segmentation or cleavage of the ovum.

the resulting coupled cell or zygote divides into two, which again encyst.

but when the zygote in its turn comes to form gametes, the partnership is broken and the process is reversed.

ix, x, show the formation of the zygote by fusion of the nuclei of the gametes.

but the problem of the way in which characters are distributed from gamete to zygote and from zygote to gamete remained as before.
mendelism reginald crundall punnett

all these things are but the transfer from zygote to zygote of something extrinsic to the species.

if the mathematical faculty has been carried in by the gamete, the education of the zygote will enable him to make the most of it.
