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:

Dendrite Cell body Axon Nervous tissue senses stimuli and transmits signals called nerve impulses from one part of an animal to another. It has a cell body, containing the cell's nucleus, and several slender extensions. One type of extension, called a dendrite, conveys signals from its tip toward the rest of the neuron; another type, the axon, transmits signals toward another neuron or to a muscle cell.

All women who participated in the study were free of cervical cancer when the test began. Pap tests were taken at regular intervals, and the researchers used a DMA probe hybridization test (Section 15.3) to detect specific types of HPV in the women's cervical cells. The results are shown in FIGURE 37.26 as a graph of the incidence rate of cervical cancer by HPV type. HPV- positive women are often infected by more than one type, so the data were sorted into groups based on the women's HPV status ranked by type: either positive for HPV16; or negative for HPV16 and positive for HPV18; or negative for HPV16 and HPV18 and positive for any other cancer-causing HPV; or negative for all cancer-causing HPV. Follow-up time (months) FIGURE 37.26 Cumulative incidence rate of cervical cancer correlated with HPV status in, 20,514 women aged 16 years and cider. The data were grouped as follows: HPV16 positive HFV16 negative and HPV18 positive All other cancer-causing HPV Types combined No cancer-causing HPV type was detected. 2. In which group would women infected with both HPV16 and HPV18 fall?
