The diploid number of chromosomes in a certain animal is 8 (2n = 8). How do the four pairs of homologous chromosomes align and separate during meiosis? All of the maternal chromosomes always move to one pole, and all the paternal chromosomes always move to the other pole O b. All 16 chromatids move together O c. Exactly two maternal and two paternal chromosomes always move to each of the two poles O d. The first to move influences all the others O e. They align and assort independently to form any of 16 different combinations

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:
