## Step 1The process that results in the production of a normal human gamete is known as meiosis. This is a type of cell division that reduces the number of chromosomes in a cell by half. ## Step 2Meiosis involves two rounds of division, known as meiosis I and meiosis II. ## Step 3During meiosis I, the cell undergoes one round of division to produce two cells, each with half the number of chromosomes (1N) of the original cell. ## Step 4During meiosis II, these two cells undergo another round of division to produce four cells, each with half the number of chromosomes (1N) of the original cell. ## Step 5The key aspect of meiosis is that it results in the production of four genetically different cells. This is because during meiosis I, homologous chromosomes exchange genetic material in a process called crossing over, leading to genetic recombination. ## Step 6Therefore, the correct answer is "Two cell divisions produce four different 1N cells." This is because meiosis involves two rounds of division and results in the production of four genetically different cells, each with half the number of chromosomes (1N) of the original cell.
