To decrease posibility of genetic diseases.
If we have only one allel and it is defected, we won't have a chance to survive. On the other hand, if we have two allel, and one is defected, the cell can use the other one.
It is one of advantages of two allel. It is also beneficial for evolution.

∙ 13y agoBecause there is always going to be a dominant an recessive gene. Therefore, two alleles are necessary.

Organism that has two diffrent alleles for a single trait?
An organism with two different alleles for a trait? is a hybrid
What oranism has two different alleles for a trait?
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
What alleles are mask in complete dominance?
A recessive trait is a trait with two contrasting alleles. In some cases contrasting alleles for a trait are codominan, that is, both are expressed.
What has two identical alleles for a trait?
A heterozygote is an organism with two different alleles for a trait.
Do alleles have to be the same trait for example Tt or can they have two traits combined for example Tb?
Alleles are the same trait
Organisms that has two different alleles for a trait?
Having two different alleles for a trait is called heterozygous.
Organism that have two identical alleles for a particular trait are said to be?
Organisms that have two identical alleles for a particular trait are said to be? homozygous
Organisms with two identical alleles for a specific trait are what?
homozygous
Organism that has two diffrent alleles for a single trait?
An organism with two different alleles for a trait? is a hybrid
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.
Organisms with two different alleles for a trait?
The organism that has two different alleles for the same trait is called heterozygous. This also refers to a cell or an individual that has two different forms of gene.
What organism has two different alleles for a trait?
[I'm not sure if you are looking for examples or a classification, but] Diploid Organisms have two copies of every gene (so they have two alleles for every trait). We are examples, so are most, if not all, Animals, and the longer portion of many Plant life cycles is also in the diploid state.
How many alleles for one trait can an individual have?
Genotypes consist of two alleles for every trait. You inherit one allele from one parent, and another from the other parent.
What do scientist call an organisms that has two different alleles for a trait?
Heterozygous.
What oranism has two different alleles for a trait?
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
A trait produced from two alleles that are alike is?
A trait that is produced from two alleles is a Homologous.
What has two like genes or alleles?
Diploid organisms, like humans, have two alternate like alleles for every gene.
