What is Co-dominant Alleles?
Two diffrent alleles at a locus, are responsible for diffrent phenotypes and both affects the phenotype
What are the phenotypes of two dominant alleles?
When taking two alles as A and a. They are AA and Aa
Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
What is it called when one trait is completely dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
Is the phenotype which determine RH?
Genotype determines the rh phenotype. The two alleles for rh factor are rh+ (rh positive) and rh- (rh negative). The rh+ allele is dominant.
What are alleles and what are the two forms?
They are traits that are passed on from parent to offspring. There are also two types of alleles; Dominant and recessive.
What is Co-dominant Alleles?
Two diffrent alleles at a locus, are responsible for diffrent phenotypes and both affects the phenotype
Can two organisms have the same phenotype and a different genotype?
Yes,if one has two dominant alleles and other has a dominant and a recessive allele
What are the phenotypes of two dominant alleles?
When taking two alles as A and a. They are AA and Aa
What are the two alleles that control the appearance of a trait?
Dominant and Recessive Alleles Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive.
What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
Why you called co-dominance when a person possess two different alleles at the same locus and both alleles are expressed in the phenotype?
Both of the parent's alleles are either dominant or recessive.
A single gene trait that has two alleles and that shows a simple dominant recessive pattern will result in?
A 3:1 phenotypic ratio (Mendelian inheritance).
If two genes in a gene pair are for the same trait what will that trait be?
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.

When one trait is not completly dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
