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 or features that are passed from parents to their offspring through reproduction. These traits can include things like eye color, hair texture, blood type, and even certain behaviors or risk factors for diseases. The primary units that govern the inheritance of these traits are called genes.
Genes are segments of DNA located on chromosomes. They act like instructions or codes that determine how certain traits will develop in an organism. Each gene carries the information needed to produce specific proteins, which in turn play a role in building and operating the body. For example, a gene might contain the code for a protein that influences skin pigmentation or the shape of your nose.
Every individual inherits two copies of each gene, one from each parent. This means that the combination of genes from both parents determines the traits that appear in the offspring. Some genes are dominant, meaning they will express their trait even if only one copy is present. Others are recessive and will only express the trait if both copies are present.
The other options in the question are related to genetics but do not specifically govern inherited traits:
- A. Hybrids refer to the offspring resulting from the cross of two different genetic lines, such as a cross between two plant varieties. While hybrids show inherited traits, they are not the source of inheritance.
- C. Purebreds are organisms that have two identical alleles for a trait, but again, the term does not describe what governs inheritance.
- D. Fertilization is the process that combines genetic material from two parents but is not what governs the traits themselves.
Therefore, the most accurate and scientific answer is genes, which are responsible for the inheritance of traits.
