half a chromosome, a chromatid.

As a species, no. A sexually reproducing species has to have an EVEN number of chromosomes.\n\nAs indivdiuals, sure. There are thousands of individuals walking around today who have 47 chromosomes.

Tetraploid. (Probably a plant)

gametes in humans are produced through meiosis. This process produces four daughter cells, each with only half of the DNA of any other cell. Normal, or autosomal cells, have 46 chromosomes, 2 pairs of each type. Sex cells, gametes, have only one of each type chromosomes, 23 total.

Trisomy is a form of aneuploidy where an organism has one extra chromosome in their genone (2n + 1). So a person with trisomy will have 47 chromosome (because a normal human has 46). A common example of trisomy is Down's Syndrome.\n\nThe n in 2n stands for the number of chromosomes in a haploid cell (a gamete, or 'sex cell') of that organism. So for humans it is 23 because a full set of chromosomes (2n) in a human is 46. It's more important to remember the 2n value of a species rather than the n value, which can easily be derived if you know 2n.\n\nMendel introduced the Law of Segregation and the Law of Independent Assortment using pea plants. Any half decent biology book can explain exactly what he did and how he derived these laws.\n\nCrossing over overs during metaphase of meiosis I (or metaphase I). More precisely, but probably not importantly, it actually occurs during prometaphase which is a phase between prophase and metaphase which was derived specifically to differentiate the process of crossing over from everything else which happens in metaphase. The teaching of prometaphase is inconsistent in courses so I would just stick with metaphase I for that answer.\n\nNondisjuction is when two chromosomes stay together instead of splitting up during anaphase, which results in the production of a cell with one extra chromosome and a cell with one less chromosome. This is the primary cause of Down's Syndrome which is related to maternal age, and other types of genetic diseases.\n\nMonosomy is the opposite to trisomy, that is, an organism has a genone with one less chromosome (2n - 1). It occurs just like trisomy. A human with monosomy will therefore have 45 chromosomes.

this was an AP Biology essay question not long ago\n\nIn mitosis ther are stages of always 46 chromosomes (23 pairs)\n\nIn meiosis in different stages it varies). Once the cell divides there are 23 chrmosomes

hi,\n\nnot all the plants are alike. different plants will have different number of chromosomes.\n\nEg: Rice (Oryza sativa) will have 12 chromosomes (n=12, 2n=24)\n\nCultivated Cotton (2n=52)\n\n wheat (Triticum, 2n=42) \n\n\nArabidopsis 2n = 10 \nRye 2n = 14 \nMaize 2n = 20 \nCultivated tobacco 2n = 48 \nFern 2n =1200\n\n B. oleracea (broccoli and cauliflower) has a haploid chromosome number of n=9 \n\n the haploid number for B. campesteris (turnip) is n=10. \n B. napus has a haploid number of n=19.

Humans have 23 unique chromosomes (called the haploid number) Each one of the chromosome is different from the all the others (unique). \nHowever we have two copies of each type of chromosome hence making 2x23=46 chromosomes called the diploid number).\nHomologous chromosome or homologs as you refer to them are the pair of chromosomes which are of the same type, and in normal humans there are always TWO of each type. Therefore the number of homologs or pairs of same chromosomes is the same as the haploid number of chromosomes i.e. 23 in normal human beings.\nAn autosome is any chromosome that is not a sex chromosome (i.e. neither a Y nor an X chromosome)

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.

In metaphase, the cell would have 8 chromosomes lined up in the middle, each made up of 2 sister chromatids. The microtubules are attached to the kinetochores and each sister chromatid is facing in the opposite direction of it's pair and towards one end of the cell.\n\nThe daughter cells would all have 8 chromosomes because it's mitosis, not meiosis.

Humans have 46 chromosomes, not 26. \n\n23 come from mom, 23 from dad.

Diploid. All cells in the body that have chromosomes, except germ line cells, are diploid. One set of chromosomes from each parent.

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.

Measuring chromosomes as a whole isn't a very good way of determining relationships between species. Although humans have 46 chromosomes (23 pairs) versus chimps' 48 (24 pairs), it's clear from looking at the structure of the chromosomes themselves that one of the human ones is composed of two of the chimps ones that have joined together. We can even see the end markers of the chimps genes in the middle of our joined one.\n\nIn terms of overall genetic difference between humans and chimps, it depends on exactly how you measure it but it's between 1 and 4 per cent. \n\nUnfortunately the answers given earlier about pigs being closer aren't accurate. They share large-scale physiological similarities, which is why heart ops may be possible, but this has nothing to do with DNA.\n\nA good reference for all this stuff is the Talk Origins archive at http://www.talkorigins.org

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.
