Inherited traits are governed by A hybrids B genes C purebreds D fertilization
The Correct Answer and Explanation is:
Correct Answer: B. Genes
Explanation:
Inherited traits are characteristics passed from parents to offspring through genetic material, and these traits are governed by genes. Genes are segments of DNA located on chromosomes that act as instructions for building and maintaining an organism’s body. Each gene carries the information needed to determine a specific trait, such as eye color, hair type, or blood type.
When organisms reproduce, they pass down their genetic material to their offspring. This genetic material includes both dominant and recessive genes, which influence how traits are expressed. For example, a child might inherit a dominant gene for brown eyes from one parent and a recessive gene for blue eyes from the other. The dominant gene will determine the child’s eye color in this case.
Let’s look at the incorrect options:
- A. Hybrids are organisms that result from the crossbreeding of two different varieties or species. While hybrids can exhibit inherited traits, they are not what governs those traits. The underlying factor is still the genes involved.
- C. Purebreds are organisms that come from a long line of the same breed or genetic lineage. Again, while these organisms pass on consistent traits, it is the genes they carry that control inheritance, not the status of being purebred.
- D. Fertilization is the process by which male and female reproductive cells combine to form a new organism. This process initiates inheritance but does not govern which traits are passed on. The traits themselves are controlled by the genes carried by the sperm and egg.
In conclusion, genes are the fundamental units responsible for inherited traits, making them the correct answer. They serve as the blueprint that determines the biological features passed from parents to their children.
