  12. 49. A chicken has 78 Chromosomes in its Somatic Cells: <ul><li>How many chromosomes did the chicken inherit from each parent? </li></ul><ul><li>How many chromosomes are in each of the chicken’s gametes? </li></ul><ul><li>How many chromosomes will be in each somatic cell of the chicken’s offspring? </li></ul><ul><li>How many chromosomes are in a “set” </li></ul><ul><li>Which came first…chicken or egg? </li></ul>

  16. 107. Question 1 <ul><li>A: What is the role of mitosis and meiosis in the human life cycle. Please be specific. </li></ul><ul><li>B: What is the difference from sister chromatids and homologous chromosomes? </li></ul><ul><li>C: Does a tumor metastasizing relate more to anchorage dependance or density-dependent inhibition? Explain. </li></ul><ul><li>D: For a cell 2n=24. How many chromosomes would be in a cell: </li></ul><ul><ul><li>D1: After Mitosis? </li></ul></ul><ul><ul><li>D2: In a gamete of this organism? </li></ul></ul><ul><ul><li>D3: In a cell after meiosis I? </li></ul></ul><ul><ul><li>D4: After meiosis II? </li></ul></ul>
  17. 108. Question 2 <ul><li>If this is a cell undergoing mitosis </li></ul><ul><li>A: What stage is this cell in? </li></ul><ul><li>B: Would you find the homologous Chromosome to chromosome 1, at 2 or 3…explain. </li></ul><ul><li>C: What stage precedes this image? </li></ul>1 2 3
  18. 109. Question 3 <ul><li>A:Which cell(s) has the spindle comletely formed? </li></ul><ul><li>B:Which cell’s DNA is entirely in the form of chromatin? </li></ul><ul><li>C:If these were human cells which cell(s) would have 46 chromosomes? </li></ul><ul><li>D: In which cells are sister chromatids connected by a centromere? </li></ul>1 2 3
