Direction: In the following questions a statement of assertion (A) is...
Assertion: Genes pass from one generation to another.
Reason: The unit of inheritance are genes.
Explanation:
Genes, which are segments of DNA, carry the genetic information from one generation to the next. This is the basis of inheritance and the reason why offspring share certain traits with their parents.
Genes are the unit of inheritance:
- Genes are the fundamental units of heredity. They are responsible for the transmission of traits from parents to offspring.
- Each gene is composed of a specific sequence of nucleotides on a DNA molecule. These sequences determine the structure and function of proteins, which play a crucial role in the development and functioning of an organism.
- During reproduction, genes are passed from parents to their offspring. This ensures the continuity of genetic information across generations.
Genes and inheritance:
- The process of inheritance involves the transfer of genetic information from parents to offspring. This information is carried by genes.
- Offspring inherit a combination of genes from both parents. This combination determines their genetic makeup and the traits they will exhibit.
- Genes can be dominant or recessive, and their expression can be influenced by various factors such as environmental conditions or interactions with other genes.
- The inheritance of genes follows certain patterns, such as Mendelian inheritance, which describes the transmission of traits through the segregation and independent assortment of genes.
- Genetic variations, resulting from mutations or genetic recombination, contribute to the diversity of traits within a population.
Conclusion:
Both the assertion and reason are true. Genes do pass from one generation to another, and genes are indeed the unit of inheritance. However, the reason provided does not directly explain why genes pass from one generation to another. It simply states that genes are the unit of inheritance, which is a known fact. Therefore, the correct answer is option B.
