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.)

∙ 9y agoDominant 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.

Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
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.
What is the opposite of homozygous of dominant?
heterozygous recessive
What gene is masked if it is paired with a dominant gene?
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.
How do dominant and recessive genes work?
explain how dominant genes work
An allele that is able to cover the recessive?
dominant allele will overthrow a recessive one
What can be dominant or recessive?
Alleles can be dominant or recessive
Comapre and contrast dominant and recessive traits?
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.
What is dominant recessive?
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 melanoma dominant or recessive?
is malignant melanoma dominant or recessive
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Is a widows peak dominant or recessive?
Dominant definitely not dominant. It is recessive objectively and subjectively and unequivocally.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
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.
