A person with the alleles ii has what blood type?
Which statement describes the blood type of a person with the alleles IAi? It is type AB because I and i are codominant. It is type AB because A and i are codominant. It is type A because i is dominant and A is recessive. It is type A because A is dominant and i is recessive.
What two alleles for the ABO blood group are not codominant?
In the ABO blood group system, the alleles A and B are codominant, meaning that when both are present, they are expressed equally. In contrast, the O allele is recessive to both A and B alleles. Therefore, when A or B is present with O, only the A or B phenotype is expressed, making O the non-codominant allele in this system.
Why is tay sachs is considered recessive level and codominant at the molecular level?
The part of tay sachs that kills you is recessive. Some proteins are still expressed even if you are a heterzygous carrier of tay sachs (less than if you are homozygous recessive but more than homozygous dominant) making the molecular view of tay sachs codominant.
What is the term that describes when both alleles show up equally?
homozygous dominant or recessive depending on what gene it is
What is it when an allele is neither dominant nor recessive?
When an allele is neither dominant nor recessive, it means that both alleles equally influence the trait. This is known as codominance, where both alleles are expressed in the phenotype of the individual.
What trait is neither dominant or recessive?
Codominant.
Is tay-sachs caused by codominant alleles?
No, autosomal recessive
A person with the alleles ii has what blood type?
Which statement describes the blood type of a person with the alleles IAi? It is type AB because I and i are codominant. It is type AB because A and i are codominant. It is type A because i is dominant and A is recessive. It is type A because A is dominant and i is recessive.
What two alleles for the ABO blood group are not codominant?
In the ABO blood group system, the alleles A and B are codominant, meaning that when both are present, they are expressed equally. In contrast, the O allele is recessive to both A and B alleles. Therefore, when A or B is present with O, only the A or B phenotype is expressed, making O the non-codominant allele in this system.
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.
Why is tay sachs is considered recessive level and codominant at the molecular level?
The part of tay sachs that kills you is recessive. Some proteins are still expressed even if you are a heterzygous carrier of tay sachs (less than if you are homozygous recessive but more than homozygous dominant) making the molecular view of tay sachs codominant.
For a codominant traiit do the offspring of identical parents always look like the parent why?
No, the offspring of identical parents would not always look like the parents because everyone has dominant and recessive traits, where the recessive traits do not show but is still in DNA. That said, recessive traits not shown in parents can be passed on as dominant traits to offspring - making offspring not always identical to its parents. (this is also called genetic variation)
Is parkinson's disease dominant recessive codominant or incomplete dominance?
Parkinson's disease is not classified as a simple Mendelian trait like dominant, recessive, codominant, or incomplete dominance. Instead, it is a complex neurodegenerative disorder influenced by multiple genetic and environmental factors. Certain genetic mutations associated with Parkinson's can exhibit a dominant inheritance pattern, but the overall condition is not strictly governed by classical inheritance patterns.
Which are differences between dominant and codominant marker?
Dominant markers show only the dominant allele and mask the recessive allele, while codominant markers show both alleles separately. With dominant markers, heterozygotes can't be distinguished from homozygous dominant individuals, while with codominant markers, heterozygotes display a distinct phenotype from homozygous individuals. Dominant markers are easier to interpret but may not provide as much information as codominant markers.
Is it impossible for two alleles to produce four phenotypes?
This would depend upon how they are expressed. Are we talking dominant, codominant, or recessive? Then there are genes thought to be fine tuned by environmental factors.
What is the term that describes when both alleles show up equally?
homozygous dominant or recessive depending on what gene it is
What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
