Sagot :
A heterozygous person that has one disease allele and one normal allele is referred to as a hybrid.
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
A heterozygous individual is a diploid organism with two alleles, each of a different type. Individuals with alleles of the same type are known as homozygous individuals. An allele is a variation of a gene that affects the functionality of the protein produced by the gene.
There can be many alleles in a population, but a heterozygous individual can only have two of them because every diploid organism receives one allele from each parent. Although each organism can have only two alleles, there can be many, many variations of a gene present in a population.
Heterozygous is a description of the genotype, or combination of alleles present in an organism. The genotype gives rise to the phenotype. Depending on the different relationships between alleles, different phenotypes are created in a heterozygous individual.
In alleles that show complete dominance, the heterozygous phenotype will be the same as the dominant phenotype. Incomplete dominance, in contrast, produces a heterozygous phenotype that is somewhere between the dominant and recessive phenotypes. A third type of relationship, codominance, exists when the different alleles are expressed individually, in different parts of the body.
In a codominant trait, the heterozygous individuals will show the phenotype of one allele on some parts of their body, and the phenotype for the other allele in different parts of the body.
