What is Co-dominant Alleles?
Two diffrent alleles at a locus, are responsible for diffrent phenotypes and both affects the phenotype
Why phenotypes don't always express its entire genotype?
Phenotypes are the entirety of the observable traits. Genotypes are the instructions in the genetic code. Dominant alleles override the recessive alleles, making only the dominant alleles expressed.
How many phenotypes does the trait have?
Aa AA aa If A dominant, two phenotypes.
What type of alleles are present in an organism?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
Gene pair that consists of two dominant alleles or two recessives alleles?
Homozygous Dominant or Homozygous Recessive, accordingly.

Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.

When a plant inherits two dominant alleles it looks like what?
wha- dominant? alleles?
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 two dominant alleles called?
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.

Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
Gene pair that consists of two dominant alleles or two recessives alleles?
Homozygous Dominant or Homozygous Recessive, accordingly.
How do you deterime phenotypes?
phenotypes are decided by the alleles for that particular characteristic, by a dominant or two recessive alleles. For example, cystic fibrosis has a recessive allele so the phenotype of cystic fibrosis would only appear if there were two of the recessive allele, one from each parent, were present. A heterozygous carrier of the cystic fibrosis allele would show the phenotype of not having cystic fibrosis. So to determine the phenotype simply find out which allele is dominant and find what alleles each parent has the the probability of each phenotype can be calculated
What is a codominance?
Co-dominant allele is the one that shows dominance with another allele from a different loci. Basically its one of the following: 1) two different alleles at a locus are responsible for different phenotypes. 2) two alleles that affect the phenotype of the heterozygote. For instance ab blood groups
