cell undergoes meiosis What happens during crossover? A. Sister chromatids and non sister chromatids physically swap places within the tetrad resulting in the mixture of entire chromatids B. Nonsister chromatids exchange parts of themselves resulting in mixing of genetic information between those chromatids C. Homologous chromosomes lineup along the equatorial play randomly mixing the maternal and paternal chromosomes along the way D.
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:
