How do cells in our organs grow
initially by mitosis and then by meiosis
initially by meiosis and then by mitosis
completely by meiosis
completely by mitosis

So mitosis is when the cell Is preparing for division. Before mitosis the cell goes through G1 which is where the cell is growing and making organelles. After G1 the cell goes through the S phase which is when the cell is replicating and copying DNA. After the S phase the cell goes through G2 which Is when the cell is preparing to divide. After that here comes mitosis which is when the cell Is getting ready for division. The cell divides in Cytokinesis which is after mitosis.

The offspring will be blood type aa, bb, ab and oo or i
