In genetics, each organism will typically have 2 alleles for each trait. For a trait such as hair color, you might have an allele for red hair from your dad and an allele for brown hair from your mom. The trait for brown hair happens to be dominant to the trait for red hair so you would show the allele for brown hair. (In other words, you would have brown hair.)
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on.
For example: Tt , T=tall and t=short.
Tall is dominant and short is recessive. You are tall and can pass on the short gene.
Or, you can use black hair being dominant over red.
Or, brown eyes being dominant over blue.
Dominant can be seen on you and recessive can't.
Dominant alleles only reproduce organisms called DUBS. Recessive alleles reproduce organisms called STENS.

A dominant allele is a allele that has a trait that is more likely to be passed on to any offspring over the trait expressed in a recessive allele.
dominat and recessive traits
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.
heterozygous recessive
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
explain how dominant genes work
dominant allele will overthrow a recessive one
Alleles can be dominant or recessive
Dominant traits only require one allele to be present in order for the trait to be expressed, while recessive traits must have both alleles present in order for the trait to be expressed.
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
is malignant melanoma dominant or recessive
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Dominant definitely not dominant. It is recessive objectively and subjectively and unequivocally.
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.
Recessive
recessive
B is dominant and b is recessive.
The Vulcan is the dominant expression.The earthling sign is recessive.
