Gene vs. allele

Abhijeet Gaurav Best Answer

A gene is a portion of that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color.Genes come in multiple forms or versions. Each of these forms is called an allele. For example, the gene responsible for the hair color trait has many alleles: an allele for brown hair, an allele for blonde hair, an allele for red hair, and so on. Function Genes govern the traits of an organism. They do so by acting as instructions to make proteinss. Proteins are the diverse molecules that play many critical roles in our bodies, such as producing hormones and creating antibodies.Humans have two copies (or alleles) of each gene, one inherited from each parent. Alleles play a significant role in shaping each human individual features. Alleles are versions of the same gene with slight variations in their sequence of DNA bases. These small differences among alleles of the same gene contribute to each person unique characteristics. Heredity Heredity is how traits are passed to offspring. Genes determine your traits, like how tall you are, what color your eyes are, and what color your hair is. But a single trait is usually determined by a number of genes, rather than just one. For example, A height alone is determined by over 400 genes.Humans and other multicellular organisms have two alleles at the same site on a chromosome. Chromosomes are very long strands of DNA wrapped around special proteins called histones. Humans have 46 chromosomes; each parent passes on 23 of those chromosomes. Accordingly, the expression of any given trait would depend on two sources of information. These two sources are a paternal allele and a maternal allele.
