Question

What percentage of eggs produced by a human female carry the X chromosome?

विकल्प

• 25%

• 75%

• 100%

• 50%

Answer 1

During oogenesis in females (XX), meiosis produces eggs that all carry a single X chromosome. Since the female has only X chromosomes, 100% of her eggs are X-bearing. This is because she has no Y chromosome to distribute to her offspring.
