State TWO ways in which cell division results in cell C being genetically different from one another. (this question going with the first question I forget to send this morning) The graph in Figure 2 shows the effect of light on the period of oestrus in two groups of female sheep. The females in the control group were subjected to the normal seasonal variation in day length. Partially through the first year of the experiment, sheep in the experimental group were subjected to reversed day-length cycle. The period of oestrus of each group of sheep is shown in solid bands above the graph (Figure 2). Using information from the graph in Figure 2, answer the following questions: i) During what months does oestrus occur in each group? ii) Give ONE advantage of this pattern of oestrus to the sheep in the control group. Explain your answer. iii) What information can be deduced from this experiment
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:
