Allergies are relatively common. Both genetics and environmental factors play a role. Allergy is caused by an oversensitive immune system, which leads to a misdirected immune response.

Recessive
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What makes a dominant allele different from recessive Allie?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
Why are two recessive alleles needed for a recesssive trait to be shown?
bcoz in case of one dominant and one recessive, dominant allele will express its characters and suppresses the recessive ones. so for the expression of recessive characters both allele should be recessive.
Is a allergie a recessive or a dominant?
It depends on the allergy, I assume. Some allergies may be recessive while others are dominant, while others still may be completely unrelated to genes.
What can be dominant or recessive?
Alleles can be dominant or recessive
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 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.
How do you xxplain dominant and recessive?
Recessive
Is AAA recessive or dominant?
recessive
When does a recessive trait dominant over a dominant trait?
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.
Which form of gene pair is expressed when both dominant and recessive are present?
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.
Is restless leg dominant or recessive?
is restless leg syndrome dominant or recessive
Is arthritis dominant or recessive?
it is dominant
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).
