WebWhen both homologues are present in a cell, the cell is said to be diploid; when only one is present, the cell is haploid. So, the gametes are _____, and the zygote is _____. For the diploid stage to yield a haploid stage, and hence complete the life cycle, the cell must divide. Draw two of these diploid cells.
