2n= 24 therefore one set consists of 12 chromosomes.

There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
There is one set of chromosomes in a shiitake mushroom cell. All of these chromosomes are located within the nucleus of the spore cell of the mushroom.
It is because with only 2-3 pairs of chromosomes we would have much less variability (Variability is critical for the existence of a population;less variability, less resistant population). Why more variability? Because we have 23 pairs of chromosomes but they are not two exactly same sets of chromosomes.

A person inherits one set of 23 chromosomes from each parent
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
Humans get 23 chromosomes from each parent, so 46 total.
In human gametes, chromosomes are not paired. Instead, each gamete has one set of 23 chromosomes, and is said to be haploid.
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
A skin cell typically contains 46 chromosomes, which are found in 23 pairs. This includes one set of 23 chromosomes from each parent.
There is one set of chromosomes in a shiitake mushroom cell. All of these chromosomes are located within the nucleus of the spore cell of the mushroom.
GAMETE
A 2n nucleus has a complete set of chromosomes. One set fro the mother and one set from the father equals two sets. A 2n nucleus has homologous chromosomes because it has one paternal homolog and one maternal homolog from the parents. So, an (n) nucleus has half the number of chromosomes and does not have any homologous chromosomes because its 2n nucleus has gone through a reductive division and now only has one set of chromosomes.
It is because with only 2-3 pairs of chromosomes we would have much less variability (Variability is critical for the existence of a population;less variability, less resistant population). Why more variability? Because we have 23 pairs of chromosomes but they are not two exactly same sets of chromosomes.
A somatic cell typically contains 46 individual chromosomes. These chromosomes exist in pairs, with one set inherited from each parent.
