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.

How many chromosomes does a human cell have normally?
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
How many chromosomes in human diploid zygote?
A normal human diploid zygote contains a full set of 46 chromosomes. A zygote refers to the initial cell that is formed when two gamete cells join together through sexual reproduction.
How many chomosones are in a human?
There are 46 chromosomes in a human, made up of 22 pairs of autosomes and one pair of sex chromosomes.
How many pairs of chromosomes do each human skin cell have?
Each human skin cell has 46 chromosomes, which are organized into 23 pairs. This includes one set of 23 chromosomes inherited from the mother and another set of 23 chromosomes inherited from the father.
How many cells form at the end of human meiosis and how many chromosomes do they each contain?
At the end of meiosis II, four haploid cells form. Haploid means they have only one set of chromosomes. For humans, that would be 23 chromosomes.
How many chromosomes does a human cell have normally?
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
How many chromosomes does a human get from each parent?
Humans get 23 chromosomes from each parent, so 46 total.
Does a normal human offspring have 2 sets of chromosomes from its father and 1 set from its mother?
No - a normal human will have 1 set of chromosomes from their father and 1 set from their mother.
How many chromosomes are in a lung cell?
A human lung cell has 46 chromosomes, as do all human body cells.
How many pairs of chromosomes found in a gametes?
In human gametes, chromosomes are not paired. Instead, each gamete has one set of 23 chromosomes, and is said to be haploid.
How many chromosomes in human diploid zygote?
A normal human diploid zygote contains a full set of 46 chromosomes. A zygote refers to the initial cell that is formed when two gamete cells join together through sexual reproduction.
How many chromosomes in normal human eggs and sperm is the same as in the body cells?
Both normal human eggs and sperm contain 23 chromosomes, which is half of the total number of chromosomes found in other body cells. When a sperm fertilizes an egg, their combined 46 chromosomes create a new organism with a complete set of 46 chromosomes.

Each human skin cell has 46 chromosomes, which are organized into 23 pairs. This includes one set of 23 chromosomes inherited from the mother and another set of 23 chromosomes inherited from the father.
How many homologous pairs of chromosomes does a diploid human cell have?
A human gamete does not have any pairs of homologous chromosomes. A single human gamete contains 23 chromosomes, or a half set. None of these chromosomes are homologous with each other.
How many cells form at the end of human meiosis and how many chromosomes do they each contain?
At the end of meiosis II, four haploid cells form. Haploid means they have only one set of chromosomes. For humans, that would be 23 chromosomes.
