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.
Alleles can be dominant or recessive
this is called codominance when alleles are neither dominant or recessive.
Dominant traits are those which are expressed even when other trait alleles are present. Recessive are those which are only expressed when the dominant alleles are not present.
Yes, recessive alleles are hidden due to the dominant alleles.
"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).
Dominant alleles override recessive alleles, but do not eliminate them. The recessive alleles can reoccur in future generations despite both parents having dominant alleles.
"Homo" means 'one' or 'the same'. Homozygous alleles are either both dominant or both recessive. In heterozygous alleles, one allele is dominant and the other is recessive
Recessive alleles can be expressed only when there is a homogenous combination of recessive alleles. That is, recessive alleles are only expressed, when there are no dominant alleles in the gene. So, 'A' being dominant and 'a' being recessive allel, the following genes have a dominant phenotype: 'AA' (homogenous dominant) and 'Aa' (heterogenous). The following have a recessive phenotype: 'aa' (homogenous recessive). All this is assuming that there are only 2-allel genes and there is no co-representation (difference in phenotype between 'AA' and 'Aa').
the dominant alleles are represented by uppercase letters and the recessive in lowercase letters.
The difference between a dominant allele and a recessive allele is that if a person inherits one dominant allele and one recessive allele the dominant allele will appear as it is stronger or more dominant than a recessive allele the dominant allele is stronger the recessive allele weaker. For instance brown eyes is a dominant allele, blue eyes is a recessive allele.A recessive allele does not always determine the trait.
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Homozygous dominant or homozygous recessive.
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
Dominant alleles :-)
Having two recessive alleles is called homozygous recessive. Having two dominant alleles is called homozygous dominant.
A gene pair that consists of two dominant alleles is called homozygous dominant, and a gene pair that consists of two recessive alleles is called homozygous recessive.
Codominance has alleles that are neither dominant or recessive.
allele can be dominant for one trait and recessive for another
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......
Dominant alleles are powerful, but sometimes recessive alleles show up which are uncommon. Some recessive alleles contain diseased that are passed onto their offspring. >.<
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
No. Dominant alleles always hide recessive. Think of it this way, dominant as in, the leader. That helps me remember that they take over. :) good luck !
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
