With reference to the chromosome, consider the following statements: I...
The correct answer is option 'A' - 1 Only.
Explanation:
1. It is a thread-like structure located inside the nucleus of animal and plant cells.
This statement is correct. Chromosomes are thread-like structures made up of DNA and proteins. They are found inside the nucleus of animal and plant cells. During cell division, chromosomes condense and become visible under a microscope. They carry genetic information and are responsible for the inheritance of traits from one generation to the next.
2. In humans, males have X and X chromosomes and females have X and Y chromosomes.
This statement is incorrect. In humans, males typically have one X and one Y chromosome, while females have two X chromosomes. The combination of sex chromosomes determines the gender of an individual. Males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). The presence of the Y chromosome in males is responsible for the development of male reproductive organs and secondary sexual characteristics.
Therefore, the correct answer is option 'A' - 1 Only.

With reference to the chromosome, consider the following statements: I...
Recently, researchers have discovered that the Y chromosome possesses genes linked to ageing and lifespan regulation.
- The Chromosome is a thread-like structure located inside the nucleus of animal and plant cells.
- Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
- It is passed from parents to offspring.
- DNA contains the specific instructions that make each type of living creature unique.
- In humans, in addition to the 22 pairs of chromosomes in each, we have a pair of sex chromosomes called X and Y.
- All biological males have X and Y chromosomes and all biological females have two X chromosomes.
- The y chromosome known as the “master of maleness,” determines the biological male sex and carries genes that play a role in sex determination.
Hence only statement 1 is correct.
