Huntington's Disease
What else can I help you with?
When a is inherited from only one parent the offspring will have that genetic condition or charicteristic?
dominant allele
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.
How does a dominant trait affect the phenotype of an organism?
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
What is the chance that any child will inherit the dominant allele if one parent does not carry the allele and the other is heterozygous for it?
The chance that any child will inherit the dominant allele in this scenario is 50%. If one parent does not carry the allele, they can only pass on the recessive allele. The parent who is heterozygous for the dominant allele can pass on either the dominant or recessive allele, resulting in a 50% chance for each allele to be inherited by the child.
What is an allele that produces a trait in the heterozygous condition called?
An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.
What gene pair is made up of one dominant allele and one ressecive allele?
A heterozygous condition resulting in the dominant genes expression in the phenotype.
Which condition is inherited as a dominant allel?
Huntington's Disease
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
Describes a trait or an allele that is expressed only when two of the alleles for the saame characteristic are inherited?
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
Is Williams syndrome dominant or recessive?
it is rarely inherited, and is often spontaneous. but when inherited, it is considered autosomal dominant condition and is usually passed down from someone with the condition to all of their offspring
Allele that prevents the expression of a recessive allele?
A dominant allele
What is a person who has a dominant and one recessive copy of a disease gene?
A person who has one dominant and one recessive copy of a disease gene is typically considered to be affected by the condition if the disease is caused by the dominant allele. In this case, the dominant allele's effects will manifest, overshadowing the recessive allele. The individual may not express traits associated with the recessive allele, as the dominant trait takes precedence.
