Dominant markers are high efficiency markers that allow the analysis of many loci per experiment without requiring previous information about their sequence.
Co-dominant markers are allows the analysis of only a single locus per experiment, so they are more informative because the allelic variation for that locus can be distinguished.
What else can I help you with?
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.
What trait is neither dominant or recessive?
Codominant.
Will A cross between two dominant homozygotes may produce a codominant animal.?
A cross between two dominant homozygotes may produce a codominant animal.
Could B is dominant to both A and O is this true or false?
False.B is dominant to O and codominant with A.
A trait requiring both genes together for expressions is called what?
Codominant
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 is codominant and dominant markers?
Dominant markers are high efficiency markers that allow the analysis of many loci per experiment without requiring previous information about their sequence. Co-dominant markers are allows the analysis of only a single locus per experiment, so they are more informative because the allelic variation for that locus can be distinguished.
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.
When phenotype of both homozygous are produced in the heterozygote they are called?
Codominance is what it is called. That is when neither allele is completely dominant over the other.
How is the prefix co related to the meaning of the term codominant?
The prefix "co-" in codominant signifies a relationship where two alleles of a gene are both fully expressed, without one being dominant over the other. In genetics, codominance occurs when both alleles in a heterozygous individual contribute equally to the phenotype.
Some alleles are neither dominant or recessive and many traits are controlled by what?
Each person has two alleles of one particular gene, which controls one particular characteristic, such as a person's blood group. An allele may be either dominant, recessive, or codominant. A dominant allele would dominate the other allele in the chromosomes, meaning only the dominant allele would contribute to an organism's characteristics. An example of this is the A blood group, which is dominant to the O allele. However, if an individual has both A and B alleles, A and B are codominant, as they both exhibit effects on an organism's characteristics (the blood group). This results in an AB blood group - a combination of the effects of two genes!
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.
