Answer:
In a diploid organism there are two copies of most genes.
The versions of the genes are called alleles.
Explanation:
Hello!
The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).
When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.
Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.
In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.
The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.

<h2>Type of Organisam to a Characteristic </h2>
The chloroplast produces food from inorganic materials. Anaerobic organelles cannot survive in the presence of oxygen this is because oxygen does not help in it's growth. Though eukaryotic cells contain cell nucleus. This is why chloroplasts produce food through photosynthesis.
Answer:
Co-dominance because he expresses both of the alleles simultaneously
Explanation:
The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.
This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
