Having just been fertilized but not yet divided, J would indicate the [zygote] stage of development. After 5 successive cell division the embryo is solid ball of 32 cells called a [morula] (H).After two more divisions (G), the embryo begins developing into a hollow ball of cells and is considered a/an [early_blastocyst].
