jack is studying the production of sperm cells and is observing the stages of meiosis. if jack is looking at a cell that is in the stage of meiosis i, which of the following is something he would not observe in a cell going through one of its phases.

• sister chromatids are separated and pulled to opposite poles of the cell.
• maternal and paternal pairs of homologous chromosomes are lining at the center of the cell.
• homologous chromosomes are separated and pulled to opposite poles of the cell.
• tetrads are visible in the cell that are most likely performing the action of crossing over.

Explanation:

Meiosis I involves pairing of homologous chromosomes (tetrads with crossing over), alignment of homologous pairs at the cell center, and separation of homologous chromosomes to opposite poles. Sister chromatid separation occurs in Meiosis II, not Meiosis I.

Answer:

Sister chromatids are separated and pulled to opposite poles of the cell.
