The dominant allele will cause the appearance of the phenotype that this dominant allele represents...
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
A form of dwarfism caused by an autosomal dominant allele is achondroplasia. It is characterized by short stature, disproportionately short limbs, and other physical abnormalities. Individuals with this condition have a 50% chance of passing on the allele to their offspring.
a example of a gene
I read in freshman biology that it is recessive. According to Barry Starr, Stanford University geneticist, bent pinky is a dominant trait.
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.
Huntington's disease is caused by a dominant allele
An autosomal disorder is one which is caused by a gene or genes on an autosome - a non-sex chromosome. Dominant means that if one allele for the disorder is present, then the person will have the disorder. For example, if H is the allele for Huntington's disease and a person has Hh - they will have the disease. Examples of autosomal dominant disorders are; Huntington's disease, Romano-Ward syndrome, Timothy syndrome and Jackson-Weiss syndrome.
Huntington's Disease
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
it depends on which allele is most dominant in the parents.
false
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.
It's caused by an dominant allele.
Huntingtons Disease
A form of dwarfism caused by an autosomal dominant allele is achondroplasia. It is characterized by short stature, disproportionately short limbs, and other physical abnormalities. Individuals with this condition have a 50% chance of passing on the allele to their offspring.
Hitchhiker's thumb is caused by a dominant allele. Individuals with at least one copy of the dominant allele will exhibit the thumb's characteristic flexibility, while those with two recessive alleles will have a straight thumb. This trait is a classic example of simple Mendelian inheritance.
If the disorder is caused by a dominant allele, you would expect to see affected individuals in every generation of the pedigree, as it only takes one copy of the dominant allele to express the disorder. Additionally, affected individuals would have at least one affected parent.
