Is waardenburg syndrome caused by a dominant or recessive allele?
Waardenburg syndrome is typically inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene is needed to develop the condition. However, there are rare cases where it can be inherited in an autosomal recessive pattern, requiring two copies of the mutated gene.
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.
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).
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
Is Lowe syndrome dominant or recessive?

Is angelman syndrome a recessive or a dominant?

Is Zellweger syndrome dominant or recessive?

Is restless leg dominant or recessive?
is restless leg syndrome dominant or recessive
Is Cockayne Syndrome a dominant or a recessive trait?
Cockayne syndrome is a recessive trait.
Is apert syndrome autosomal or sexlinked?
Apert syndrome is a autosomal dominant genetic disorder, meaning that only one copy of the mutated gene from either parent is necessary to inherit the condition. It is not sex-linked.
Is servant syndrome dominant or recessive?
There is no servant syndrome, It is likely that you are thinking albeit with bad spelling of Savant Syndrome. and it is recessive
Is tourette syndrome dominate or recessive?
semi-dominant--semi-recessive
Is Down syndrome a dominant or recessive?
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
How do you get Apert syndrome?
Apert syndrome is a genetic defect, so that means that the child will have it from conception (it's an autosomal dominant genetic defect, which means that only one parent needs to supply the defective gene in order for the child to be born with it.)
What are two forms of robinow syndrome?
Dominant and recessive
Is down syndrome cause by dominant or recessive?
Down syndrome is neither caused by dominant or recessive chromosomes it is simply caused by an error in the translation process of chromosome 21.
