No, codominance is a genetic relationship between two versions of a gene where both versions are expressed in the phenotype. In contrast, recessive traits are only expressed when an individual has two copies of the recessive allele.
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.
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.
homozygous dominant or recessive depending on what gene it is
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.
Codominance is a genetic phenomenon where two different alleles for a trait are expressed equally in the phenotype of an organism. An example of codominant alleles is the ABO blood group system, specifically the A and B alleles. When an individual inherits both the A and B alleles, their blood type is AB, displaying characteristics of both types without blending, which illustrates that neither allele is dominant or recessive. This results in both A and B antigens being present on the surface of red blood cells.
Codominant.
No, autosomal recessive
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.
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.
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.
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)
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.
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.
homozygous dominant or recessive depending on what gene it is
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.
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
O blood type can only receive O blood type because in genetic, O is has recessive alleles while other types of blood has codominant alleles. A recessive alleles cannot combine with dominant or codominant allels. So if a person who has blood type O receive the other types of blood besides O, the blood cells within that person is going to repel each other. The worst situation, the person can die.
