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.

- During sexual reproduction, fertilization of the ovum (n, 23 chromosomes) by the sperm (n, 23 chromosomes) restores the diploid number and creates a zygote (2n, 46) (awww..) that divides and grows by mitosis to form a multicellular human.

Meiosis If a sperm containing 46 chromosomes fused with an egg containing 46 chromosomes, how many chromosomes would the resulting fertilized egg contain? Do you think this would create any problems in the developing embryo?

Human reproduction The sperm and the ovum are known as gametes (each containing half the genetic information of the parent, created through meiosis). The sperm (being one of approximately 250 million sperm in a typical male ejaculation) travels through the vagina and cervix into the uterus or Fallopian tubes.

- Answer   i think 26     Answer   i think 26     Answer   46 chromosomes. The sperm cell and egg cell each contain 23 chromosomes, totalling … 46. The sperm cells and egg cells are known as haploid cells or sex cells (meaning having 1 set of chromosomes).Once the sperm cell and egg cell joins, a diploid cell is formed (meaning having 2 sets of chromosomes), and a zygote begins to form. The human body contains 2 sets of chromosomes, one maternal and one paternal.he sperm cells and egg cells are known as haploid cells or sex cells (meaning having 1 set of chromosomes).

Ploidy Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n). Retroviruses that contain two copies of their RNA genome in each viral particle are also said to be diploid.

Sexual reproduction All cells in a higher eukaryote (like us) are diploid ­ EXCEPT...for the germ cells ­ eggs and sperm. Germ cells have only half the number of chromosomes as a diploid cell ­ one of each pair - and are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. The number of chromosomes is reduced from 46 to 23 during the process of meiosis. Fertilization of the egg by the sperm restores the diploid number of 46 chromosomes.

- Unlike the body's other cells, the cells in the egg and sperm — called gametes or sex cells — possess only one chromosome. Gametes are produced by meiosis cell division, which results in the divided cells having half the number of chromosomes as the parent, or progenitor, cells. In the case of humans, this means that parent cells have two chromosomes and gametes have one. All of the gametes in the mother's eggs possess X chromosomes.

Spermatogenesis During this cell division there is a splitting of the nuclear material. In the nucleus of the primary sperm cells there are 46 chromosomes; in each of the secondary sperm cells there are only 23 chromosomes, as there are in the egg. When the egg and sperm combine and their chromosomes unite, the characteristics of both individuals blend and the new organism starts to grow.

- exists and is an alternate of . Haploid, or gametic, human Cells have a chromosome number of n which is 23 individual chromosomes. The Gametic human sperm Cell has the chromosome number n = 23 [unpaired] chromosomes; in the also gametic human Oocyte (egg Cell), n also = 23.

- This is significant as when fertilization occurs, the zygote (sperm + ovum) will have 46 chromosomes (or 23 pairs), the normal number for a human. So, both the ovum and spermatid are haploid sex cells (gametes), each with 23 chromosomes in humans.

- Sperm and egg cells are haploid cells, meaning they have half the number of chromosomes as all other cells in the body. Humans have 46 chromosomes, so human reproductive cells will have 23.he sperm contains one copy of each of the 22 autosomal chromosomes and either one X or one Y chromosome. After fusion, these pair up to form a diploid cell, so that there are 46 chromosomes-two of each of the 22 autosomal chromosomes, and either two X chromosomes, or one X and one Y chromosome.

Expectations The gametes are haploid (n) meaning they only have one copy of each type of chromosome that the diploid (2n) parent cell contains. The first part of meiosis reduces the chromosome number from diploid to haploid (reduction division). Human gametes contain n = 23 chromosomes compared to the 2n = 46 chromosomes found in somatic cells. Each human sperm or egg cell contains 22 autosomes and one sex chromosome (either X or Y).

How sperm and eggs develop precisely 23 chromosomes each How sperm and eggs develop precisely 23 chromosomes each. April 12, 2012. There are many tools that cells could use to separate DNA strands that cross over during meiosis. UC Davis researchers have identified the right tools for the job. Researchers at the University of California, Davis have discovered a key tool that helps sperm and eggs develop exactly 23 chromosomes each.

How many chromosomes are in sperm cells? There are 23 chromosomes in human sperm cells. Both sperm and ovum (eggs) are known as gametes, which are the cells that participate in sexual reproduction. Normal gametes c … ontain exactly half the number of chromosomes of a normal (non-sex) cell.

Meiosis and meiotic errors (Genetics) The human egg and sperm cells carry 23 chromosomes. These cells are  considered haploid cells containing half of the number of  chromosomes of other human cells.he sperm contains one copy of each of the 22 autosomal chromosomes and either one X or one Y chromosome. After fusion, these pair up to form a diploid cell, so that there are 46 chromosomes-two of each of the 22 autosomal chromosomes, and either two X chromosomes, or one X and one Y chromosome.

Meiosis For example, diploid human cells contain 23 pairs of chromosomes including 1 pair of sex chromosomes (46 total), half of maternal origin and half of paternal origin. Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.

How Many Chromosomes Are Contained in a Human Male Gamete Cell? The human male gamete, also known as a sperm cell, contains 23 chromosomes in total. Humans have 22 chromosome pairs as well as two sex chromosomes, for a total of 46 chromosomes. The gamete produced by each sex contains half, or 23, of these chromosomes.

- Therefore there is a total of 23 pairs of chromosome in a human body cell. However the human gametes formed by meiosis have haploid number of chromosomes i.e. they have only 23 chromosomes instead of 46; so that after fertilization the zygote has 23 pairs of chromosome(23 from the sperm and 23 from the ovum). There are 23 pairs(46 chromosones)of chromosones in a human body cell.

Aneuploidy Most cells in the human body have 23 pairs of chromosomes, making a total of 46. Individual sperm and egg cells, however, have just 23 unpaired chromosomes. You received half of your chromosomes from your mother's egg and the other half from your father's sperm cell.

How sperm and eggs develop precisely 23 chromosomes each Healthy humans have 46 chromosomes, 23 from the sperm and 23 from the egg. An embryo with the wrong number of chromosomes is usually miscarried, or develops disorders such as Down's syndrome, which is caused by an extra copy of chromosome 21.

A sperm cell of a grasshopper contains 12 chromosomes. how many chromosomes would a grasshopper body cell hold In sex cells, the number of chromosomes will always be half that of a normal body cell under normal conditions (There may be exceptions due to mutations or other factors. One example is Down's Syndrome, where the sufferer has 47 chromosomes instead of 46 due to an extra chromosome 21).he Diploid Number is usually twice that of the Haploid Number. Hence, since the sperm cells contains 12 chromosomes (Haploid), THE NUMBER OF CHROMOSOMES FROM A DIPLOID CELL WILL HAVE 24 CHROMOSOMES. Source(s): GCE O Level Candidate.

How many chromosomes do you have in your gametes? 23 Gametes (eggs and sperm) need to have half the normal chromosome number OS that when they combine the create a normal (or diploid) cell with 46 chromosomes.
