Correct Answer - Option 3 : Genes
Genes:
- A gene is the basic physical and functional unit of heredity.
- In biology, a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein.
- Genes are made up of DNA.
- Genes are passed from parents to offspring and contain the information needed to specify traits.
- Genes are arranged, one after another, on structures called chromosomes.
-
Identical twins share all of their genes and are always of the same sex.
Heredity:
- Heredity refers to the genetic heritage passed down by our biological parents.
- It is the transmission of traits from one generation to the next.
- These traits can be physical, such as eye color, blood type or disease, or behavioral.
Hence, the basic conductors of heredity are considered genes.
