The third allele can typically be found in the genetic makeup of an organism, specifically in the DNA sequences located on chromosomes. Alleles are variations of a gene, and in a diploid organism, there are usually two alleles for each gene—one inherited from each parent. However, in cases of multiple alleles, such as in blood type systems (like the ABO blood group), a third allele may exist in the population alongside the two common alleles. This third allele can be identified through genetic testing or analysis of the organism's genotype.
What else can I help you with?
If an allele for a particular trait is NOT expressed at all when another allele for the trait is present the allele is .?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps

The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
Every allele is a what allele?
No! they are different
A man has one recessive allele and one dominant allele. what is his phenotype?
He would have the recessive phenotype for that trait.
Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.

What is an example of allele frequency?
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
What is the phenotype of an individual with one allele for dimple and one allele for no dimples?
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
Would a recessive allele or dominant allele be more common in population?
Dominant allele because its more likely to be received by the next generation.
What is the phenotype of an individual with one allele for dimples and one for no dimples?
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
How do you deterime phenotypes?
phenotypes are decided by the alleles for that particular characteristic, by a dominant or two recessive alleles. For example, cystic fibrosis has a recessive allele so the phenotype of cystic fibrosis would only appear if there were two of the recessive allele, one from each parent, were present. A heterozygous carrier of the cystic fibrosis allele would show the phenotype of not having cystic fibrosis. So to determine the phenotype simply find out which allele is dominant and find what alleles each parent has the the probability of each phenotype can be calculated
Every allele is a what allele?
No! they are different
How do you find allele frequency in a population?
To find allele frequency in a population, you can calculate it by dividing the number of copies of a specific allele by the total number of alleles in the population. This can help determine how common a particular gene variant is within a group of individuals.
A fly has two alleles for the color of its eyes The green allele is recessive and is represented by q The blue allele is dominant and is represented by p If 20 of 100 organisms are green what is?
A. 0.45 Apex
A man has one recessive allele and one dominant allele. what is his phenotype?
He would have the recessive phenotype for that trait.
If straight hair is genetic why do you have straight if none f your ancestors did?
it is because the parents each were heterozyous dominant. meaning each of them had a dominant allele and a recessive allele. the dominant allele would be the curly hair, and the recessive allele would be the straight hair. There would be a 1/4 chance that the child would have curly hair, and a 3/4 chance that they would have curly hair. Say that the Curly hair allele was H and the straight hair allele was h. In order for the parents to have curly hair, they would either have to have an HH gamete or an Hh gamete. Seeing as though the child came out with curley hair, both parents would have to have an Hh gamete. In order to find out the probability, you multiply the parents gametes. (Hh)(Hh). This will give you HH, Hh, Hh, hh. seeing has three of the gametes have the dominant allele, this child will have curly hair, and one is a homozygous recessive, so it will turn out with straight hair.
