How many chromosomes does a sperms have if it’s lacking a sex chromosome?

The normal number of chrom's in an adult human cell is 23 pairs (46 intotal). Insex cells it is 23 single chrom's. (23 in total). So without the sex chrom', the sex cell, wether the ovm or sperm, would have 22 chro's ie 23 - 1 = 22.

Totally 46 chromosomes.\n22 pairs will be there and two sex chromosomes will be there.\nIf male, X & Y and If Female X & X.\nSo totally 46.

A human parental cell (or germ cell) has 46 chromosomes or 23 pairs (2n).

If you are talking about Somatic division (mitosis) , just before division the mother cell will  have 23x2 chromosome pairs that is 23x2x4 chromatids in all. The daughter cells get 23x2x2 chromatids=23 pairs of chromosomes each. In case of meiosis, one more division leads to 23 singlet chromosomes (=23x2 chromatids) each in a daughter cell.

Well the cat gametes are hapliod which mean that hey have half of the normal body cells.  They are haploid because when joined with mate they combine together to form a zygote.\n\nNow to get the number of chromosomes for the zygote just divide the number of chromosomes for the body cells and their you have the number of chromosomes that gametes have and them mutiply by 2 to get the fertilization # for the zygote.

I honestly do not know, but "chromosoms" has an E: chromosomes.

An egg, and a sperm both contain a nucleus which holds half of our DNA (23 chromosomes). All of our other cells contain 46 Chromosomes. In the lab, they harvest an egg from which ever species they are cloning, and they remove the nucleus. They can then take the nucleus of a normal 46 chromosome cell and put it inside the egg- where it's nucleus used to be. The egg then "thinks" it is fertilized and will start to divide, and grow. This embryo is an exact replica of the parent cell. Cloning is a form of asexual reproduction, because sex was not involved in the creation of the new embryo. There are many ethical issues surrounding cloning. Some argue that scientists are "playing God" because they are creating new life. Some say that if a human were to be cloned- it would have no soul because it was not created by God. There are too many ethical issues to type here, but you get the idea. You'll have to decide for yourself where you stand. Hope this helps. good luck in school

Down syndrome is not inherited. It happens when something goes wrong in the formation of either the egg or the sperm. Normal people recieve a copy of each chromosome from both parents. People with down syndrome have an extra copy of chromosome 21.  When one of the sex cells was developed, the two copies didn't get pulled apart when they should have during meiosis.

Your mother donates 23 chromosomes and your father donates 23 giving you 46 chromosomes total. Mutations, such as Trisomy-21, do occur where people can have less or more which usually results in some form of genetic disease.

Both parents for the organisms that the cell is living in!\nIn order to be a functional cell, it needs 46 chromosomes.\n23 of them come from the organisms mother, and 23 from the organisms father.\n\nIt isn't talking about the organism this gamete may become, but rather the parents of the organism that the meiosis is going on in...

150 sperm cells....\nbecause each secondary spermatocyte shall become a spermatid each...and each spermatid produces a sperm cell.... therefore, a sec. spermatocyte only produces a single sperm cell...

The X-chromosome in humans has about 1045 genes on it, and the Y only has 5. So the chances of a Y-linked disorder are slim (1/209). \n\nIn females, having two X chromosomes means that both would have to have the bad copy of the gene to express the trait. Males, with only one X, express whatever is on that chromosome, good or bad.

Probably has to do with x & Y chromosomes has to do with genetics to make baby a boy or girl

human cells contain 46 chromosomes\n\nthey go through a process of mitotic division that basically replicates each chromosome, the original and replicated chromosomes then migrate to opposite ends of the cells, and a cell membrane is formed, thus producing two progeny cells, division and the cycle of the cell is complete.\n\n\nmeotic division is a more complex process, but basically, the daughter cells contain 23 chromosomes, that is 1 of each pair of the 46 chromosomes is present in the daughter cell, where, whether it is a sperm or egg cell, when fused together, provide the fused cell with 46 chromosomes\n\n\n\n\nhope it helped you understand it a little better\n\nthere are however, different phases to the division process and if you like I can send you a link, depends on how much you want to know at present?

its triploid,that means three sets of chromosomes.one from the haploid sperm of the pollen grain and two from the diploid secondary nucleus present in the embryo sac of the ovule,in the ovary.got it now!

If it is a diploid (2n) and has 30 chromosomes, then it has 30 chromosoms obviously but one usually addresses these as 15 pairs and not 30 chromosomes. The haploid of this would thus be 15 single chromosomes.

In Turner syndrome, the girl does not have the usual pair of two complete X chromosomes. The most common scenario is that the girl has only one X chromosome in her cells. Some girls with Turner syndrome do have two X chromosomes, but one of the X chromosomes is incomplete. In another scenario, the girl has some cells in her body with two X chromosomes, but other cells have only one.
