No, all alleles at a specific gene locus are not identical. Alleles are different forms of a gene that can result in different traits or characteristics. Each individual inherits two alleles for each gene, one from each parent. These alleles may be the same (homozygous) or different (heterozygous).
What else can I help you with?
What is the difference between a factor and an allele?
A locus is a particular location or a marker on a chromosome. It can be a gene but really only needs to be an identifiable location on the chromosome. Alleles differ in that they refer to a particular sequence of DNA at a given locus. The distinction from loci is that multiple alleles can exist for the same locus. http://www.informatics.jax.org/silverbook/glossary.shtml
What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
Where is location of different alleles of the same gene?
One of the different alleles would be at the same gene locus on each of the paired chromosomes.
How are terms gene locus and allele related?
A gene locus refers to the specific position of a gene on a chromosome, while an allele refers to different versions of the same gene that can exist at a particular locus. In other words, a gene locus is the physical location of a gene on a chromosome, while an allele is a specific variant or form of that gene found at that locus.
True or false even if a gene has alleles a person cannot have more than three of those alleles?
True. A person can have at most two alleles for a given gene, one inherited from each parent. While a gene can have multiple alleles in the population (more than two), an individual can only possess a maximum of two alleles at any specific gene locus.
What is the term for when an organism has two identical alleles for a trait?
The term is homozygous.This means that the alleles of a particular gene, at a particular locus on a specific chromosome, are the same.
An individual with two identical alleles of a gene is?
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
Having a pair of alleles the same is called?
A pair of alleles which are the same are said to be homozygous.
Alleles of a gene are found at the same locus on heterologous chromosome true or false?
False. Alleles of a gene are found at the same locus on homologous chromosomes.
What is the definition of homozygus?
Homozygous -It is the characteristic of having two identical alleles at the same locus of sister chromatids.homozygous means having identical alleles at corresponding chromosomal locus or the specific site of a particular gene on its chromosome
What are pure alleles?
Alleles come in pairs. Organisms inherit one allele from each parent organism with sexual reproduction. If the alleles are the same, they could be said to be pure alleles. The science term is monozygous.
What is the difference between a factor and an allele?
A locus is a particular location or a marker on a chromosome. It can be a gene but really only needs to be an identifiable location on the chromosome. Alleles differ in that they refer to a particular sequence of DNA at a given locus.

Is A heterozygous pair of alleles is identical?
When there are heterozygous alleles for a gene thy code for a different expression of the gene. For example, the gene to taste PTC paper is a single gene trait. A person will have two copies (or alleles) for that gene (one from their mothers DNA, one from their father). There are two possible expressions for this gene - either you can taste the chemical or you cannot. When one allele is for tasting, and the other for not tasting, this is known as heterozygous. Both alleles are relating to the same gene but they giving different instructions and are thus not identical. When this happens, the dominant gene wins - in this case tasting is expressed. If the alleles are identical, they are known as homozygous and they are identical.
What is homozyous?
"Homozygous" refers to an individual having two identical alleles for a particular gene. This can either be two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive). Homozygosity increases the likelihood of genetic traits being expressed.
Can you please distinguish homozygous and heterozygous individuals?
Homozygous individuals have two identical alleles for a particular gene (e.g., AA or aa), while heterozygous individuals have two different alleles for the same gene (e.g., Aa). Homozygous conditions often result in specific traits, while heterozygous conditions can lead to a blending or mix of traits from each allele.
What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
Where is location of different alleles of the same gene?
One of the different alleles would be at the same gene locus on each of the paired chromosomes.
