Crossing over is important within meiosis because it allows __ A. for cells to be genetically identical B. for cells to be genetically unique C. the chromosomes to separate correctly

## Step 1<br />Crossing over is a process that occurs during meiosis, specifically in the prophase I stage. This process involves the exchange of genetic material between homologous chromosomes. <br /><br />## Step 2<br />This exchange of genetic material results in new combinations of genes on each chromosome. This means that the cells produced after meiosis will have a unique combination of genes, which is different from the parent cell.<br /><br />## Step 3<br />This process of crossing over increases genetic diversity among the offspring. This is because the new combinations of genes on each chromosome result in unique genetic traits in the offspring.<br /><br />## Step 4<br />Therefore, the purpose of crossing over is not to create genetically identical cells (option A), nor is it to ensure the correct separation of chromosomes (option C). Instead, it is to create genetically unique cells (option B).
