4. Adult human females carry gametes arrested in Meiosis I. True or false?
4. Adult human females carry gametes arrested in Meiosis I. True or false?
Homework Answers
answer. False because before puberty female gametes arrested in Meiosis 1 but when they attain puberty [adult] the Meiosis starts again and it also arrested in meiosis 2 until a sperm does not meet it. when sperm meet it then female gamete continue meiosis and fertilization occurs.
