A dikaryotic cell develops into a zygote whena. mitosis divides the two nuclei into separate cells, which thencombine at fertilization.b. mitosis occurs without cytokinesis.c. the two haploid nuclei within the cell fuse.d. meiosis occurs once and cytokinesis occurs twice.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
A dikaryotic cell develops into a zygote when
a. mitosis divides the two nuclei into separate cells, which then
combine at fertilization.
b. mitosis occurs without cytokinesis.
c. the two haploid nuclei within the cell fuse.
d. meiosis occurs once and cytokinesis occurs twice.
