What is the difference between dominant and recessive alleles on the basis of DNA?
Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait.
:::::::::::::::brown eyes overrided blue eyes, because they are darker::::::::::::::::::
usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......
What else can I help you with?
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
What is the difference between homozygosity and heterozygosity?
Homozygosity refers to having two identical alleles for a particular gene (e.g., both alleles are dominant or both are recessive), while heterozygosity refers to having two different alleles for the same gene (one dominant and one recessive allele). In homozygosity, an individual's genotype is either homozygous dominant or homozygous recessive, whereas in heterozygosity, the genotype is a combination of both dominant and recessive alleles.
What is the difference between heterzygous and homozygones?
Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles for the same gene. Homozygotes can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygotes have one dominant and one recessive allele.
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What is the relation between dominant and recessive alleles?
the dominant trait is the stronger one and the recessive trait is the weaker one

What is the difference between the dominant and recessive allele for a trait?
An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
What is the interaction between dominant and recessive alleles?
This inter action is called dominance .
What is the difference between homozygosity and heterozygosity?
Homozygosity refers to having two identical alleles for a particular gene (e.g., both alleles are dominant or both are recessive), while heterozygosity refers to having two different alleles for the same gene (one dominant and one recessive allele). In homozygosity, an individual's genotype is either homozygous dominant or homozygous recessive, whereas in heterozygosity, the genotype is a combination of both dominant and recessive alleles.
Differences between dominant and recessive?
Dominant is stronger than recessive. So you can only have the phenotype ( visual characteristic ) of a recessive allele if you have 2 recessive alleles in your DNA , and other combination the dominant allele would be predominant
What is the difference between homzyguos and heterozyous?
Homozygous refers to having two identical alleles for a particular gene (e.g., two alleles for blue eyes). Heterozygous refers to having two different alleles for the same gene (e.g., one allele for blue eyes and one allele for brown eyes).
A genetics tool that uses letters to represent dominant and recessive alleles?
A punnet square uses letters to represent dominant and recessive alleles.
What is the difference between dominant and recessive gene?
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
What is the difference between heterzygous and homozygones?
Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles for the same gene. Homozygotes can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygotes have one dominant and one recessive allele.
