It is certainly possible to have more than 46 as in Trisomy 21 (or down syndrom) where "one cell has two 21st chromosomes instead of one, so the resulting fertilized egg has three 21st chromosomes".

How many chromosomes does each skin have?
each skin cell has 46 chromosomes
How many chromosomes are contained in a human male gamete cell?
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
How is the nucleus of the sperm cell different to the nucleus in the body cell?
a gamete nucleus has only half the number of chromosomes in it than a regular body cell. in humans a regular body cell has 46 chromosomes (23 pairs) in the nucleus, but a gamete ie sperm or egg cell has only 23 chromosomes, which are all unpaired. during fertilization the 23 chromosomes from a sperm and the 23 from the egg cell combine and pair up.
Which cell contain 46 chromasomes?
All of them (in humans), apart from sperm and egg cells (which contain 23)
How many chromosomes are present in a sperm cell before fertilization and in the zygote after fertilization?
There are 22 in each, along with an X sex chromosome for the female form and a Y sex chromosome for the male form.
What chromosome is abnormal in a human karyotype?
when the chromosomes is 47 or less than 46
What is the process call when a human cell may have more or less than 46 chromosomes as a result of nondisjunction?
Chromosomes fail to separate during cell division (its in the lesson)
Whether each and every human cell posses 46 chromosomes?
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.
What is 46 less than 12?
46 less than 12 is -34.
A human cell may have more or less than 46 chromosomes as a result of nondisjunction a process in what?
chromosomes fail to separate during cell division
Can humans have more than 46 chromosomes?
No, that's the number of chromosomes in a normal human somatic cell, but not all living things have that number. Drosophila (fruit fly) for instance, only have four, and are a model for genetics for that reason and others.
If a parent cell has 46 chromosomes how may chromosomes will the daughter cells have?
They will also have 46 chromosomes.
How much chromosomes does a person have?
There are 46 chromosomes in each cell. However, there are 23 in a sex cell e.g. 23 in an egg cell, 23 in a sperm cell to form 46 chromosomes for a embryo to develop.
Number of chromosomes in a human body?
Each cell has 46 chromosomes. Eggs and sperm each have 23, thus a human has 46.
How many chromosomes are in one human cell?
46 single chromosomes which is 23 pairs of chromosomes in one human body cell.
How many chromosomes does a muscle cell have?
A muscle cell has a diploid number of chromosomes, which is 46. The germ cells, such as the sperm and egg, have 23 chromosomes.
What happens if you have more or less chromosomes?
If you have one additional pair of CHROMOSOME 23, you have DOWN SYNDROME.If a person has fewer than 46 chromosomes, they will die. With more than 46 chromosomes, it depends on the chromosome type , but mostly disorders or syndromes will occur. Death is also a possibility in this case.AnswerThe condition wherein the number of chromosomes in a individual is more or less than the expected number of chromosomes is called aneuploidy.Examples include Down's Sydrome (three sets of chromosome 21), Klinefelter's syndrome (one extra X chromosome in males), Turner's syndrome (one X chromosome less in females), Edward syndrome (extra chromosome 18).
