1. The problem statement, all variables and given/known data A cell with 16 chromosomes undergoes meiosis. One of the then formed cells (at the end of meiosis 2) gets fertilized by an unknown gamete. The zygote formed from this fertilization undergoes mitosis 3 times. How much DNA-strands will there be at the end, only taking into account the fertilized cell (so not the three other cells formed in meiosis) ? 3. The attempt at a solution 1. The cell with 16 chromosomes undergoes meiosis, so there are 4 cells with 8 chromosomes in the end. 2. One of them is fertilized by an unknown gamete, so nowe have 16 chromosomes again. 3. The formed zygote undergoes mitosis 3 times, meaning at the end there will be 2^3 cells with 16 chromosomes each. My answer: in the end there will be 8x16 or 128 dna strands. This seemed pretty easy to me, almost too easy, so I would like to know if I did it right. Thanks !
