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.
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
is malignant melanoma dominant or recessive
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
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
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
is restless leg syndrome dominant or recessive
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
it is dominant
recessive.
It is recessive
