Which of the following statements is not true?
Correct answer: D. Aldohexoses exist in 2 optical forms
- A. Glucose and fructose both are monosaccharides
- B. The natural glucose and fructose are D-forms
- C. The solution having equal molecules of D-glucose and D-fructose is termed inverted sugar
- D. Aldohexoses exist in 2 optical forms
Explanation
This statement is not true. Aldohexoses, including glucose, exist in multiple optical forms. For example, D-glucose and L-glucose are two optical isomers of glucose. Therefore, option D is the correct answer. So, the correct answer is option D: "Aldohexoses exist in 2 optical forms."

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
