Answer: option B - some gametes may have an extra copy of some genes.
Explanation:
Actually, nondisjunction occurs in meiosis and results in FOUR ABNORMAL GAMETES/DAUGHTER CELLS: two gametes have an EXTRA copy of gene e.g XXY, while two other gametes LACK a required copy e.g XO
So, the right answer is some gametes may have an extra copy of some genes.
The primary function of the lymphatic system<span> is to transport </span>lymph<span>, a fluid containing infection-fighting white blood cells, throughout the body. The </span>lymphatic system<span> primarily consists of </span>lymphatic<span> vessels, which are similar to the circulatory </span>system's<span> veins and capillaries.</span>
