What are genes and alleles?

Answer 1

The functional part of DNA is a gene. All the DNA in an organism does not code for protein. In fact, only a fraction of the genome codes for protein. The part of the DNA that codes for protein is called a gene. Different forms of the same gene are called alleles. There are alleles controlling phenotypic features such as eye color and height of the individual Although these features are controlled by the same gene, different features can result depending on which allele is expressed.

Answer 2

A gene is a sequence of DNA that codes for the production of a transcript, that usually would be translated into a protein.

An allele is a version of the gene as it appears on a chromosome. People inherit one chromosome each from mom and dad, so each person has two alleles for any single gene.

Answer 3

Genes are the basic units of heredity that carry instructions for the development, functioning, and reproduction of organisms. Alleles are different forms of a gene that can result in variations in traits such as hair color or height.Each parent contributes one allele per gene, which determines the genetic makeup of an individual.
