The correct Answer is:
To solve the question, we need to evaluate each of the three statements provided and determine whether they are true (T) or false (F). ### Step 1: Evaluate the first statement **Statement:** "Failure of segregation of homologous chromosomes during cell division leads to aneuploidy." - **Analysis:** The process of segregation refers to the separation of homologous chromosomes during cell division, particularly during the anaphase stage of meiosis or mitosis. If this segregation fails, it results in aneuploidy, which is an abnormal number of chromosomes in a cell. This statement is true. ### Step 2: Evaluate the second statement **Statement:** "Polyploidy is more common in plants." - **Analysis:** Polyploidy refers to a condition where an organism has more than two complete sets of chromosomes. This condition is indeed more common in plants than in animals due to the flexibility of plant genomes and their ability to adapt to environmental changes. This statement is also true. ### Step 3: Evaluate the third statement **Statement:** "Non-haemophilic parents cannot have a haemophilic child." - **Analysis:** Hemophilia is a genetic disorder that is often inherited in an X-linked recessive manner. A non-haemophilic mother can be a carrier of the hemophilia gene (if one of her X chromosomes carries the gene), and if she has a son, there is a possibility that he could inherit the hemophilic gene from her. Therefore, it is possible for non-haemophilic parents to have a hemophilic child if the mother is a carrier. This statement is false. ### Conclusion Based on the evaluations: - Statement 1: True (T) - Statement 2: True (T) - Statement 3: False (F) The correct option is that the first two statements are true, and the third statement is false. ### Final Answer 1. True (T) 2. True (T) 3. False (F) **Correct option:** 3rd option (T, T, F) ---

Chromosomal disorders are caused due to absence or excess or abnormal arrangement of one or more chromosomes. Failure of segregation of chromatids during cell division cycle results in the gain or loss of a chromosome, and is called aneuploidy. Failure of cytokinesis after telophase stage of cell division results in an increase in a whole set of chromosomes in an organism and, this is known as polyploidy. There are a total number of .......... pairs of autosomes in a normal human cell.
