no, normally humans do have 46, but certain mutations or genetic disorders can result in more, less, or fused chromosomes. the most common example of missing chromosomes is down's syndrome. when someone has an extra chromosome(s) it's called polyploidy. i can't tell you too much about fused 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 chromosomes are usually found in human cells?
A single human cell contains 23 pairs of chromosomes (22 autosomes and a pair of sex chromosomes ). These are found in all human cells (RBC's and platelets being exception ). So with human body made up of unbountable number of cells, the actual number of chromosomes in the human body is unbountable times 46= unbountable.
Why does the nucleus of a fruit fly contain less chromosomes than the nucleus of a human?
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
How many single chromosomes are in a human gamete?
A human gamete contains 23 single chromosomes. Gametes are haploid cells, meaning they have half the number of chromosomes compared to diploid somatic cells, which contain 46 chromosomes. Each gamete, whether sperm or egg, carries one set of chromosomes, which is crucial for sexual reproduction. When two gametes fuse during fertilization, they restore the diploid number of chromosomes in the resulting zygote.
Why is duplication of chromosome required before mitosis?
Because every cell in the human body contains the formula for our chromosomes. If the chromosomes don't reproduce, then new duplicate cells cannot be formed.
In your body what do you have 46 of?
Every human should have 46 chromosomes in his or her body. 23 chromosomes come from a human's mother and 23 chromosomes come from a human's father.
How many chromosomes does a human have.?
Every normal human cell has 46 chromosomes (23 pairs), so every human gamete has 23 chromosomes. Rarely, a human cell might have an extra chromosomes and that some times causes the death of the embryo or a deformity like Down's.
How many chromosomes does your cells have?

How many chromosomes are in a normal human diploid cell?
every human have 46 chromosomes haploid(23)+haploid(23)=46 chromosomes
How many chromosomes s in the human body?
Every human being has 23 pairs of chromosome which translates into 46 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.
Skin cells have how many pairs of chromosomes?
Yes, any cell of an organism, whether it be a skin cell, brain cell, muscle cell, or other, has chromosomes. Humans have 23 unique chromosomes which come in pairs in every cell of their body.
How many chromosomes are usually found in human cells?

So with human body made up of unbountable number of cells, the actual number of chromosomes in the human body is unbountable times 46= unbountable.
How many chromosomes are there in human body?
Normally, every somatic cell in the human body contains 46 chromosomes.
Human cell contains how many chromosomes?
Every single cell, regardless of being human or not, contains chromosomes, but only when dividing or reproducing. It cells' normal state, their DNA is not wound up in chromosomes, but freely floating around the nucleus.
Why does the nucleus of a fruit fly contain less chromosomes than the nucleus of a human?
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
