Which of the following is true about genes?
*
Genes are responsible for all the traits of an organism.
In humans, genes are passed to an offspring from two parents.
Genes are made up of smaller molecules known as chromosomes.
The genes of a particular organism can never change throughout its lifetime
Genes are responsible for all the traits of an organism.
The correct answer is:
Genes are responsible for all the traits of an organism.
The correct answer is:
Genes are responsible for all the traits of an organism.
To determine the correct answer, we can analyze each option:
1. Genes are responsible for all the traits of an organism. This statement is true. Genes contain the instructions that determine the characteristics, traits, and functions of an organism.
2. In humans, genes are passed to an offspring from two parents. This statement is true as well. In sexual reproduction, each parent contributes a set of genes to their offspring, resulting in a combination of genetic traits.
3. Genes are made up of smaller molecules known as chromosomes. This statement is incorrect. Chromosomes are structures that contain the DNA, which carries the genes. Genes are specific segments of DNA.
4. The genes of a particular organism can never change throughout its lifetime. This statement is false. While the genetic material of an organism remains relatively stable, changes in genes can occur due to mutations, genetic recombination, or environmental factors. These changes can lead to variations in traits or the development of new traits over time.
By analyzing each option and understanding the basics of genetics, we can determine that option 1 is the correct answer.
