These are terms used in a punnet square. Dominant is the Phenotype, or a gene that is predicted to be expressed in a heterozygous being- the offspring of two beings with different traits. Recessive is the Genotype, or a gene that is predicted to be hidden in the Deoxyribose Nucleic Acid, (DNA,) of a heterozygous being. Sometimes there is Codominance, where both genes are fully expressed, or incomplete dominance, where the genes are mixed, and are partially expressed.

∙ 13y agoA dominant gene will hide the recessive gene. It is shown as a capital letter in the gene. (i.e. Rr, R is the dominant gene) In blood type, A is dominant over O. So if a person has Ao for their genes, they will have A type blood.
A recessive gene will be hidden unless there are two of the same recessive gene. It is shown as a lowercase letter in the gene (i.e. Rr, r is the recessive gene). In blood type, O is the recessive allele, so you cannot have O type blood unless you have 2 O alleles: oo.

∙ 13y agoIf we were talking about eye colour and the blue eye gene came from your dad (recessive) and the brown from you mum (dominant) then the dominant gene would over power the recessive gene you would end up with brown eyes. That's just the basics it can get alot more confusing. Btw I was just taking a guess about which 1 is recessive and which is dominant

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
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.
