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.
An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
The term used to describe organisms that consistently pass the same form of a trait to their offspring is "homozygous." Homozygous organisms have two identical alleles for a particular gene, meaning they express the same trait consistently. This contrasts with "heterozygous" organisms, which have two different alleles for a gene and may express a mix of traits.
The mating of organisms with different homozygous alleles for a single trait is referred to as a monohybrid cross. In this scenario, one parent possesses two dominant alleles (homozygous dominant), while the other has two recessive alleles (homozygous recessive). The offspring produced from this cross will be heterozygous, displaying the dominant trait, while the recessive trait will not be expressed in the phenotype. This type of cross is often used to illustrate basic principles of Mendelian inheritance.
Homozygous individuals have two identical alleles for a specific trait. This means they can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles). Homozygosity results in the expression of either the dominant or recessive trait.
Organisms that have two identical alleles for a particular trait are said to be? homozygous
homozygous
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.
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.
An organism with two different alleles for a trait is said to be heterozygous for that trait. This means that it has one dominant allele and one recessive allele. The dominant allele will usually determine the organism's phenotype for that 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.
An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.
Heterozygous.
An individual can have a maximum of two alleles for one trait, as they inherit one allele from each parent. These alleles can be the same (homozygous) or different (heterozygous) for a specific trait.
An organism that has two identical alleles for a trait is said to be homozygous for that trait. This means that both alleles are the same, either dominant or recessive. Homozygosity results in a consistent expression of the trait in the organism.
An organism that possesses two different alleles for a trait is said to be heterozygous for that trait.
The term used to describe organisms that consistently pass the same form of a trait to their offspring is "homozygous."
