What is the difference between alleles and multiple alleles?

Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid). A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance. So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles) Yes, or: Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.


What are different versions of the same gene called?

Different versions of the same gene are called alleles. Alleles can differ in their DNA sequence, resulting in variations in the traits they encode for. These variations can lead to differences in an organism's phenotype.


Different versions of the same gene are known as what?

Different versions of the same gene are known as alleles. Alleles can vary in their nucleotide sequence and can result in different traits or characteristics in an organism.


What are some alternative forms of genes?

Some alternative forms of genes include alleles, which are different versions of the same gene, and gene duplications, where a gene is copied multiple times within an organism's genome. Additionally, genes can undergo mutations that lead to different forms or variants known as gene variants or polymorphisms.


Many people use the terms gene and allele interchangeably Are they the same please explain?

Genes and alleles are not the same. Genes are sections of DNA that determine specific traits, while alleles are different versions of the same gene that can affect how a trait is expressed. A gene can have multiple alleles, each contributing to variations in traits.
