Question

The plant Haplopappus spp. Is diploid and 2n = 4. There are one long pair and one short pair of chromosomes. The figure below represent anaphases of individual cells in meiosis or mitosis in a plant that is genetically a dihybrid (A/a; B/b) for genes of different chromosome. The lines represent chromosomes or chromatids, and the points of the V’s represent centromeres. In each case, the figure represents a cell in meiosis I, meiosis II, mitosis or an impossible situation.

• A. 1 – Meiosis I, 2 – Mitosis, 3 – Meiosis I, 4 – Meiosis I
• B. 1 – Mitosis I, 2 – Mitosis, 3 – Meiosis II, 4 – Meiosis II
• C. 1 – Impossible, 2 – Meiosis – II, 3 – Impossible, 4 – Impossible
• D. 1 – Impossible, 2 – Mitosis, 3 – Meiosis I, 4 – Meiosis II

Answer 1

Answer: (C)

1 – Impossible, 2 – Meiosis – II, 3 – Impossible,

4 – Impossible
