  5. 21. A Chromosome made of DNA – Replicated during Interphase that is divided equally during mitosis.

  6. 22. The number of chromosomes in offspring would double the number of parental chromosomes. Organism would not survive, or the number of chromosomes would be unmanageable.

  7. 23. The G1 stage of the cell cycle is the phase of cell growth. This is followed by the S stage, during which DNA is copied. G2 involves the cell preparing for cell division. The M phase is when mitosis occurs. The cell cycle concludes with cytokinesis. The newly formed cell then enters into a new cell cycle .

  8. 24. During mitotic metaphase , the diploid number of chromosomes of the cell line up single file across the equator of the cell. Meiotic metaphase I is chraraterized by the homologous chromosomes lining up as pairs (TETRADS) along the equator of cell. Metaphase II is similar to mitotic metaphase, except the number of chromosomes is haploid rather than diploid.

  9. 25. Offspring from sexual reproduction have two parents. They were produced through meiosis and fertilization. They are genetically different from either parent but have similarities to both. Offspring from asexual reproduction arise through mitosis in one parent. They are identical genetically to that parent.
