13, defintly, dude it's half

Human cells have 46 chromosomes. To ensure that each daughter cell receives one and only one of each chromosome, eukaryotic cells undergo a complex, multistep process called mitosis. Before mitosis can begin, eukaryotes must first replicate their DNA. This process is similar to but takes much longer than DNA replication in prokaryotes. Then, during mitosis, the replicated chromosomes line up along the center line of the cell. Tiny fibers, called spindle fibers, attach to the individual chromosomes and pull them apart, toward opposite poles of the cell, where they remain until the cell divides.\n\nLong story short, the new skin cell will still have 46 chromosomes.

During meiosis, sexually reproducing organisms choose one of the two versions of each chromosome they have (the two versions are supplied because each parent provides one copy of each chromosome) to be included in the haploid gametes. Because one copy of two possible choices has to be made for each of the 4 chromosomes (diploid number of 8 is referring to the fact there are 2 copies of each of 4 chromosomes meaning 8 total). \n\nTo figure out the number of possible combination you use a simple probability formula. \n\nThere are 2 choices for the first chromosome location x 2 possible choices for the second location x 2 possibilities for the third location x 2 possibilities for the final location\n\n2x2x2x2 = 16 possible combinations that can be made in any one gamete.\n\nOf course this is the absence of any crossing over event, which can produce an incalculable number of possible rearrangements.

Unfertilized ova as well as sperm are haploid, meaning they contain only one set of chromosomes. These are the only cells in the organism which have only half the number of chromosomes. We can say that haploid is "n". Diploid cells contain both sets from the mother and father, so it is "2n".\n\nThe zygote is basically an embryo which is the by-product of a fertilized ovum. It therefore has 14 chromosomes from the mother and 14 from the father, so 28 total. This assumes that all goes well. Sometimes there are chromosomal abnormalities but in the vast majority of cases the zygote has twice the number as the unfertilized ovum ("egg") as well as the sperm.

i have 56 chromosomes...im special

For humans, we need a 1 pair of chromosomes (#1-23).  If we didn't reduce our chromosome, the next generation would carry 2 pairs of chromosomes and that would be incompatible with life.  Our sexual cells (sperm and egg) has 1 set (not a pair of them) of chromosomes so that the set from the egg and the set from for sperm together makes a human with 1 pair of chromosomes.

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.

Meiosis is a completely different process from mitosis.\n\nI should stop doing other people's homework...\n\nMeiosis ends with a different amount of cells, and the cells as a result of meiosis only have 1/2 of the chromosomes of the original cell, where in mitosis, the daughter cells have the same amount of chromosomes.\n\nIn meiosis, there are two divisions. \n\nMeiosis occurs only in reproductive cells. For example, in humans, sperm has 23chromosomes and eggs have 23 chromosomes, a normal human cell has 46, which is why it takes two reproductive cells to create a living thing.\n\nI could go on and on, but I have to return to my own work.

12 linear chromosomes in the nucleus, plus plasmids in the ~100 chloroplasts, and circular chromosomes in the ~100mitochondria. Note that each mitochondria has many identical chromosomes.

It is haploid, only having 23 chromosomes until it is fertilized. Then it is diploid with 23 pairs(46 total) of chromosomes, and is capable of growing into a baby.

46 chromosomes or 23 pairs of chromosomes per cell, consisting of 22 pairs of autosomes, and two sex chromosomes; considering the body has over a trillion cells...\n That is basically 46,000,000,000,000 chromosomes!\nThere are some rare cases when there is an extra chromosome(ex: Downsyndrome) or one less chromosome in each cell.

Assuming we're talking about humans ...\n\nIn the female gamete (the ovum, or egg cell) the DNA in the nucleus is contained in 23 chromosomes.  One of these is the sex chromosome, but this is always an X chromosome.  Outside the nucleus are additional pieces of DNA ... most notably, DNA in the mitochondria of the cell, which will get passed intact to the offspring.\n\nIn a male gamete (spermatozoan or sperm cell) the DNA in the nucleus is also contained in 23 chromosomes.  One of these is the sex chromosome and is either a Y or an X chromosome.  This will determine the gender of the offspring.  Sperm cells also have DNA in their mitochondria, but these are discarded upon fertilization (so the offspring gets mitochondrial DNA exclusively from the mother).\n\nUpon fertilization, the two gametes make a zygote.  The 23 chromosomes from each (haploid) gamete produces a complement of 46 total chromosomes in the (diploid) zygote.  The pair of sex chromosomes determines the gender of the developing offspring ... XY is a boy, XX is a girl.

The paired (diploid) number of chromosomes for Struthio camelus (ostrich) is reported as 80. You can see a karyotype at the link.

26\n\nIn meiosis, the chromosome pairs are divided in half so the new cell has 1 of each.  This is because this is used to produce cells for reproduction.\n\nWhen 2 of these cells come together,they create 52 chromosomes again to create a new organism with half of each parents genetic material.

23.  Each chromosome will be paired with its homologous partner to form a tetrad in Prophase 1.  Since the human body has 46 chromosomes and since each will pair with its homologue there will be 23 tetrads present.

Let's assume you want a human example.\nHuman cells have 46 chromosomes.\n\nIn Meiosis 1:\nProphase 1- chromosomes replicate, join with homologous pairs to become tetrads.\n--46 chromosomes paired, 23 tetrads, and 92 chromatids\nMetaphase 1- same numbers as prophase\nAnaphase 1: 46 chromosomes (double stranded), 92 chromatids\nTelophase 1: end: 23 chromosomes (double stranded), 46 chromatids per cell\n\nProphase 2: same as Telophase 1\nMetaphase 2: same as Telophase 1\nAnaphase 2: 46 chromosomes, zero chromatids\nTelophase 2: end: 23 chromosomes per cell.

No, because we are the only ones that have 46 chromosomes 23 from mon , 23 from dad             First, the sperm and eggs in nearly all species have membrane proteins that recognize same-species gametes--human eggs will only recognize human sperm, goat eggs will only recognize goat sperm, etc. Secondly, for a human (or any other animal, for that matter) to be viable, it must have the correct number of chromosomes. Normal adult human cells have 46 chromosomes (23 derived from the mother, 23 derived from the father). Dogs have 76 chromosomes in each of their cells (38 of maternal origin, 38 of paternal origin).
