Different allele combinations can result from non-disjunction in meiosis I or II respectively. Please refer to your Module 12 worksheet for how these allele combinations were generated in gametes. Based on this principle, which of the following can explain why XYY was produced? A. Non disjunction in the mom meiosis I. B. Non disjunction in the mom meiosis II. C. Non disjunction in the dad meiosis I. D. Non disjunction in the dad meiosis II.
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:
