Is an allele the same as a gene?

Answer 1

An allele is a kind of gene. Example: gene=eye color. Allele=blue eye color

Answer 2

Sort of. An allele is any given sequence for a particular gene- an analogy would be a book. Suppose a book is a gene. Some books have lots of different versions, first edition, condensed edition, paperback edition, etc, all slightly different, but more or less the same. Those variant forms are alleles.

Answer 3

No. A gene determines a characteristic. An allele is a version of a chromosome.

Both mom and dad have genes determining eye color.
Mom gives a blue allele, Dad gives a brown allele.
The genes of the baby will most likely determine it's eyes to be brown, the dominant allele.

Answer 4

In genetics, an allele (pronounced al-eel or al-e-ul) is any one of a number of viable DNA codings occupying a given locus (position) on a chromosome. Usually alleles are DNA (deoxyribonucleic acid) sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. An individual's genotype for that gene is the set of alleles it happens to possess. In a diploid organism, one that has two copies of each chromosome, two alleles make up the individual's genotype.

Answer 5

NONONONONO! Don't listen to them!

A gene is a specific trait. An allele is a part of the chromosome that codes for the trait.

Ex: You have genes for blood types. But there are 3 alleles: A, B, and i.

Answer 6

Please listen to the last 4 answers only, an allele is a particular version of a gene.

Answer 7

an allele is a variation of a gene

Answer 8

In genetics, an allele (pronounced al-eel or al-e-ul) is any one of a number of viable DNA codings occupying a given locus (position) on a chromosome. Usually alleles are DNA (deoxyribonucleic acid) sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. An individual's genotype for that gene is the set of alleles it happens to possess. In a diploid organism, one that has two copies of each chromosome, two alleles make up the individual's genotype. The word came from Greek αλληλος = "each other".

An example is the gene for blossom color in many species of flower—a single gene controls the color of the petals, but there may be several different versions (or alleles) of the gene. One version might result in red petals, while another might result in white petals. The resulting color of an individual flower will depend on which two alleles it possesses for the gene and how the two interact.A gene is the unit of heredity in every living organism. Genes are encoded by nucleic acid molecules such as DNA or RNA, and direct the physical development and behavior of the organism. Most genes encode proteins, which are biological macromolecules comprising linear chains of amino acids that affect most of the chemical reactions carried out by the cell. Some genes do not encode proteins, but produce non-coding RNA molecules that play key roles in protein biosynthesis and gene regulation. Molecules that result from gene expression, whether RNA or protein, are collectively known as gene products.

Most genes contain non-coding regions, that do not code for the gene products, but often regulate gene expression. A critical non-coding region is the promoter, a short DNA sequence that is required for initiation of gene expression. The genes of eukaryotic organisms often contain non-coding regions called introns whose transcripts are removed from the messenger RNA in a process known as splicing. The regions that actually encode the gene product, which can be much smaller than the introns, are known as exons.

The total complement of genes in an organism or cell is known as its genome. The genome size of an organism is loosely dependent on its complexity; prokaryotes such as bacteria and archaea have generally smaller genomes, both in number of base pairs and number of genes, than even single-celled eukaryotes. However, the largest known genome belongs to the single-celled amoeba Amoeba duria, with over 6 billion base pairs.[1] The estimated number of genes in the human genome has been repeatedly revised downward since the completion of the Human Genome Project; current estimates place the human genome at just under 3 billion base pairs and about 20,000-25,000 genes.[2] The gene density of a genome is a measure of the number of genes per million base pairs (called a megabase, Mb); prokaryotic genomes have much higher gene densities than eukaryotes. The gene density of the human genome is roughly 12-15 genes/Mb.[3]
