What are alleles that have an effect on an organisms phenotype?

The presence of more than two alleles for a trait is known as probility. There might be one which is dormant and the others which are recessive.

Do both alleles of a gene pair make up an organisms genotype?
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
What are inactive alleles?
Inactive alleles (usually called recessive) are not fully expressed in the phenotype of the organism.
The external appearance of an organism as determined by what alleles are present is?
Phenotype
Do all heterozygous pairs alleles produce an intermediate phenotype?
No
An individual's description of that organisms particular combination of alleles is known as what?
A Phenotype
How does codominance effect phenotype?
both alleles are expressed in the offsping
In what alleles can be observed in the phenotype?
you mean phenotype, and its dominant alleles
Do both alleles of a gene pair make up an organisms genotype?
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
When both alleles can be observed in a phenotype the interaction is called?
When both alleles contribute to the phenotype of a heterozygous the alleles are said to show the dominate alleles and sometimes the recessive but mostly the dominate alleles
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.
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
Do alleles control phenotype?
yes
What is a phenotype-?
A phenotype is the physical trait or feature of an organism that is the effect of a particular genotype. Flower color of snapdragons is one example of a phenotype, and the color is determined by which alleles comprise the genotype. Plants that are homozygous for the flower color alleles are either white or red. Heterozygous snapdragons are pink.
What is it when the presence of two different alleles results in an intermediate?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
What is the interaction of two alleles in which both alleles can be observed in a phenotype?
Incomplete dominance
