विकल्प

Answer 1

The unit of inheritance is gene.

Explanation:

The gene is considered the fundamental unit of inheritance. It is a hereditary unit that controls a specific function or leads to the expression of a particular phenotypic trait. Genes are segments of DNA located on chromosomes and are responsible for transmitting characteristics from one generation to the next. They are the smallest units that can undergo mutation or recombination. Over time, the gene concept has evolved, but it remains the basic unit controlling heredity and genetic information transfer.
