How many chromosomes does a human egg cell contain? Best Answer: A human body cell would have 46 chromosomes. Since a human egg cell is a reproductive cell (sex cell), it would contain only half the number of chromosomes as a body cell. Thus, a human egg cell would have 23 chromosomes. A sex cell has half the number of chromosomes for a good reason. When two sex cells reproduce, they combine to form double the number of chromosomes. So when two cells with 23 chromosomes each reproduce, the offspring would have 46 chromosomes. To keep humans at 46 chromosomes per cell, sex cells are produced through meiosis, which is a process that creates cells with half the number of chromosomes.

Meiosis Somatic cells (body cells) are haploid cells. They have 23 pairs of chromosomes. Reproductive cells (gametes) have half the normal number i.e. 23. This is because two gametes (one male and one female) have to fuse hence, restoring the original number of 23 pairs.here are 46 total chromosomes in a normal human body cell. They pair up, creating 23 pairs of chromosomes. Mutations can occur during cell division, causing human cells to have a varied amount of chromosomes-more or less. There are many genetic diseases caused by chromosomal mutations.

How many chromosomes do human body cells have? 46 Chromosomes in the Human body cells. Body cells have pairs of chromosomes while sex cells have only single sets of chromosomes. The human body cells have 22 pairs of autosomes and 1 pair of sex chromosomes for a total of 23 pairs or 46 chromosomes. Sex cells for humans will have half of that (because they are not paired) so a total of 23 chromosomes. 23 pairs. The short answer is 46 chromosomes in the human body cell. </zzz>.

Chromosome 9 Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 9, one copy inherited from each parent, form one of the pairs. Chromosome 9 is made up of about 141 million DNA building blocks (base pairs) and represents approximately 4.5 percent of the total DNA in cells. Identifying genes on each chromosome is an active area of genetic research.

How many chromosomes and how many chromatids? Here is the way I think about it: before S phase, a typical human cell contains 46 chromosomes. During S phase, all 46 chromosomes are replicated. Because they are identical copies, it is perfectly fine to say that there are now 92 (46 + 46) chromosomes in the cell.

How many chromosomes do humans have in each cell? Humans have 46 chromosomes in each cell. During fertilization of the egg, the sperm nucleus containing 23 chromosomes from the paternal side fuses with the nucleus of the egg that contains 23 chromosomes from the maternal side. The result is the zygote that contains 46 chromosomes (23 pairs of chromosomes; one of each pair from either parent). From that single celled zygote comes all the cells of your body today that is formed as a result of uncountable number of cell divisions.

How many chromosomes are in a sperm cell? in an egg cell? in a white blood cell? Best Answer: In humans, you would find 23 chromosomes in a sperm cell; 23 chromosomes in an egg cell; and 46 chromosomes in a white blood cell. All human body cells contain 46 chromosomes (two sets of 23 chromosomes). Only the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells. Body cells grow and reproduce by the process of mitosis.

- Millions in the human body. Each cell has 23 pairs of chromosomes that have genetic importance. 22 of these are autosomes and one sex chromosome. The 22 determine traits and sex chromosomes determine the gender - XX develops into female and XY develops into male. Hence, there are (23 x 2) 46 chromosomes in the human cell.

The number of chromosomes in a human gamete is zygote-originating from the haploid number 23 in the gamete. This depends on the species of the egg.
