Answer: Diploid; 2n
Explanation:
In many species, there are two representatives of each chromosome. In such species, the characteristic number of chromosomes is called the DIPLOID number. It is usually symbolized as 2n.
The two basic sets of chromosomes is called Homologous chromosomes, being two, it is called DIPLOID NUMBER (if one, it is Haploid number) and symbolized by 2n.
Species like man expresses the diploid number, so is a diploid specie
Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles.
<h3>What is phenotype?</h3>
Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles. We will recall that the HbS allele is responsioble for the anemia that results from sickle shaped red blood cells.
This phenotype is both harmfull and benefical in the sense that it leads to the agglutination of the red blood cells in individuals that have this phenotype and eventual crisis. Also, it is beneficaila in that nthose who possess this phenotype do not suffer from malaria in the tropics.
