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 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 are in a normal human body?
46.The cells of the human body, for example in the liver, brain, and muscles, contain two sets of chromosomes, and are called diploid. There are 23 chromosomes in each set, and we inherit 23 from each parent.
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 are there in one set of chromosomes in lilium?
2n= 24 therefore one set consists of 12 chromosomes.
How many chromosomes are in one of your skin cells?
23.Human cells, except for sex cells (gametes), are diploid, which means they have one set of 23 chromosomes from Dad (paternal chromosomes) and one set from Mom (the maternal ones).
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 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 are in a normal human body?
46.The cells of the human body, for example in the liver, brain, and muscles, contain two sets of chromosomes, and are called diploid. There are 23 chromosomes in each set, and we inherit 23 from each parent.
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.
Does a normal offspring have 2 sets of chromosomes from its father and 1 set from it mother?
No - a normal human will have 1 set of chromosomes from their father and 1 set from their mother.
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 are there in one set of chromosomes in lilium?
2n= 24 therefore one set consists of 12 chromosomes.
How many chromosomes do human egg cells and sperm cells have?
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
How many chromosomes are in one of your skin cells?
23.Human cells, except for sex cells (gametes), are diploid, which means they have one set of 23 chromosomes from Dad (paternal chromosomes) and one set from Mom (the maternal ones).
How many chromosomes are there in one full set of chromosomes in the grey wolf?
39
How many chromosomes does a human haploid cell have?
The haploid number is the number of chromosomes within the nucleus of a cell that constitutes one complete chromosomal set. This number is commonly abbreviated as n, where n stands for the number of chromosomes. The haploid number will be different for different organisms. In humans, the haploid number is expressed as n=23.Haploid human cells have 1 set of 23 chromosomes:Autosomal chromosomes (non-sex chromosomes): 22 sets.Sex chromosomes: 1 set.Diploid human cells have 2 sets of 23 chromosomes for a total of 46 chromosomes:Autosomal chromosomes: 22 sets of 2.Sex chromosomes: 1 set of 2.
