Final answer:

Genes are DNA sequences that determine traits and can have different versions called alleles. Genes are found in every cell and play a crucial role in inheritance.


Explanation:

A gene is a specific deoxyribonucleic acid (DNA) sequence that codes for a specific polypeptide or protein or an observable inherited trait. This basic biological unit transmits characteristics from one generation to the next.

Genes are sequences of DNA that code for a particular trait. Different versions of a gene are called alleles - sometimes alleles can be classified as dominant or recessive.

For example, in pea plants, a given gene might code for flower color.
