**Title: Understanding Meiosis and Chromosomal Disorders**---**Question 1: Non-Disjunction in Meiosis 2**If a non-disjunction occurs in meiosis 2 in a male and the resulting sperm fertilizes a normal female egg, which of the following could result? Check all that apply.- [ ] a) YO- [ ] b) XYY- [ ] c) XXY- [ ] d) XXX- [ ] e) XO---**Question 2: Formation of Polar Bodies**Polar bodies are formed during:- ( ) Male meiosis- ( ) Female meiosis- ( ) Both male and female meiosis- ( ) Neither male nor female meiosis---**Question 3: Chromosomes in Brain Cells**A brain cell in a normal human male would have a Y chromosome.- ( ) a) True- ( ) b) False--- **Explanation of Concepts:**1. **Non-Disjunction and Its Consequences:** - Non-disjunction is the failure of chromosome pairs to separate properly during cell division, specifically in meiosis. This can lead to conditions like Klinefelter syndrome (XXY) or Turner syndrome (XO).2. **Polar Bodies:** - Polar bodies are small cells that are by-products of oocyte development in female meiosis, which plays a critical role in reducing chromosome numbers by half.3. **Chromosomal Composition of Cells:** - In normal human males, somatic cells, including brain cells, contain both an X and a Y chromosome. Gametes, however, carry only one sex chromosome.**Note:** The above information aims to clarify the processes and potential outcomes related to chromosomal distribution during meiosis.
