All humans have 46 chromosomes (23 pairs). in the nucleus of every single cell in our body, excluding the red blood cell which has no nucleus.
Each pair of chromosomes has certain genetic coding (one set from each parent). Without these chromosomes sperm and eggs wouldn't know what to do in order to form a baby. And if my some miracle they did, that baby's cells wouldn't know what their job is, so just wouldn't function.
Therefore our skin cells wouldn't exists, neither would our bone cells, etc. So we would just stay as a blob of stem cells (only stem cells which can't change into anything else).

xx is a girl and xy is a boy.

Does mitosis produce a complete set of the chromosomes?
YES Mitosis is cell division, its job is to separate the cell and to do that it has to copy the chromosomes. everything including a complete set of chromosomes.
Do heart cells have a complete set of chromosomes and DNA?
The only cells that doesn't have a complete set of chromosomes are germ cells (also called sex cells, or gametes).
How many chromosomes in a complete set?
Chromosomes are condensed DNA within a cell. Strands of DNA(deoxyribonucleic acid) are tightly wound around proteins called histones. These groups of clustered DNA and histones are compacted into a substance known as chromatin. The chromatin condenses into chromosomes. There are 23 pairs of chromosomes within each cell throughout the whole body. This is vital for survival of multicellular organisms as DNA holds the genetic code for the organism and also the information for certain proteins to be produced by the cell. In short, there are 23 pairs of chromosomes in every cell, and chromosomes are made up of DNA - the genetic code.
What cells have a complete set of chromosomes?
All human cells have a complete set of chromosomes. Every single human cell has the same genetic information, but each cell specializes in which information it uses specifically based on the function of the cell.
What is a gamete having more than one complete set of chromosomes?
Meiosis is a process of cell division that produces gametes in organisms that sexually reproduce. A gamete having more than one complete set of chromosomes cannot be produced by meiosis.
The number of chromosomes in sex cells relative to the body cells?
there are half the number of chromosomes in sex cells than in body cells because the sex cell needs to combine with another to complete its set of chromosomes
In plants what is meant by saying that the cells of a sporophyte phase are dipliodor 2n?
it just means that the gamete has a complete set of chromosomes. haploid means that the gamete does not have a complete set of chromosomes and needs another haploid cell (typically this is sperm and egg) to fuze with it and create a zygote with a complete set of chromosomes.
Do Body cells contain pairs of chromosomes?
Yes. Because a haploid contains 23 chromosomes and in order for it to be a diploid it must have a complete set of chromosomes. Therefor a diploid would be a complete set of chromosomes.
Why isen't fertilization considered to be complete until the nuclei of the two cells join together?
because there needs to be a full set of chromosomes, 46

YES Mitosis is cell division, its job is to separate the cell and to do that it has to copy the chromosomes. everything including a complete set of chromosomes.
Is it true that a haploid nucleus has half the number of chromosomes as the parental nucleus as well as one chromosome of each type?
Yes, using humans as examples, gametes, or sex cells, contain 1 complete set of 23 chromosomes, which is half the number in the body cells. The 1 complete set of 23 chromosomes contains genetic material from both parents due to crossing over during prophase I of meiosis. Having one set of chromosomes is said to be haploid. In body cell there are two complete sets of 23 chromosomes. One set comes from each parent. In human body cells there are 46 chromosomes. This condition is said to be diploid.

What do you call a cell with complete set homologous chromosomes?
diploid
What is the purpose of somatic cells?
Somatic cells are body cells that contain a full set of chromosomes. I imagine that a somatic cell donor donates healthy body cells to someone who needs them.
