The correct Answer is:
To solve the question regarding the statements about the genotypes and their implications, we can break it down step by step. ### Step-by-Step Solution: 1. **Understanding Statement I:** - Statement I claims that the genotype 2A + X0 represents Turner syndrome in women. - Turner syndrome is a condition that affects females and is characterized by the absence of one X chromosome. The typical genotype for Turner syndrome is indeed represented as 45,X or 2A + X0 (where A represents autosomes and X represents the sex chromosomes). - Therefore, Statement I is **correct**. 2. **Understanding Statement II:** - Statement II states that the genotype 2A + X0 represents a normal male in grasshoppers. - In grasshoppers, the male genotype is typically represented as 2A + X0, where A represents the autosomes and X represents the sex chromosome. This means that the male grasshopper has one X chromosome and no second sex chromosome. - Thus, Statement II is also **correct**. 3. **Conclusion:** - Both statements are correct. Therefore, the answer to the question is that both Statement I and Statement II are correct. ### Final Answer: Both statements are correct.
