Although the exact cause of MS is still unknown, multiple sclerosis isn't considered a hereditary disease in the traditional sense.
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
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).
