Tetraploid means they have four sets of chromosomes, one set originally came from a male lizard. Since the eggs require only one complete set of chromosomes to be fertile, they are fertile from birth of the lizard that produces them. The subsequent offspring from these eggs, to their fourth generation, retain that four sets of chromosomes in their own genetic makeup. Therefore their eggs will be fertile and hatch without further introduction of male sperm............Does it make sense now?...........
“”Does it make sense now?...........””
What confused me was that I thought the mothers were triploid. But now a new question arises. If the mothers are tetraploid, the process of meiosis would produce diploid eggs (supposedly fertile) to create a diploid offspring. How are the offspring tetraploid?
