Why is it necessary to reduce the chromosome number of gametes but not other cells of an organism

why is it necessary to reduce the chromosome number of gametes but not other cells of an organism Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells blue whales have 44 chromosomes in every cell determine how many chromosomes you would expect to find the following.

Best answer: because 2 gametes must combine to create an embryo if each gamete had the full number of chromosomes, the child would end up with double the number of chromosomes of the preceding generation. Best answer: gametes have less chromosomes then other cells so that the offspring has the same amount of chromosomes as the parents humans have 46 chromosomes, but we only have 23 pairs of chromosomes (two pairs of chromosome 1, two pairs of chromosome 2 etc. Gametes are not body cells, they are sex cells they must have only 23 chromosomes since they will give only half to their offspring during sexual reproduction.

9 why is it necessary to reduce the number of chromosomes in gametes but not in other cells if the liver cells of an animal have 24 chromosomes how many chromosomes do its sperm cells have choose one answer a 6 b 12 c 24 d 48. Meiosis is a reduction divisionthat is necessary in sexually reproducing organisms to maintain the species number of chromosomes gametes, or sex cells must have half the chromosomes that the.

Gametes are responsible for the mixing of two cells together the germ cells if the cell was complete with the full number of chromosomes, then they could not join to become once cell. Meiosis (/ m aɪ ˈ oʊ s ɪ s / ( listen) from greek μείωσις, meiosis, which means lessening) is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.

If humans have 46 chromosomes in each of their body cells, determine how many chromosomes you would expect to find in the following: sperm _____ egg _____ daughter cell from mitosis _____ daughter cell from meiosis ii _____ 9 investigate a disease that is caused by chromosomal mutations. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells it necessary to reduce the number of chromosomes in. Why is it necessary to reduce the chromosome number in gamete cells (egg and sperm), but not other cells of an organism cite source(s) used (2 pts) to have a child through sexual reproduction, they have to jumble up their genes and combine them together using their gametes. Why is it necessary to reduce the number of chromosomes gametes by one half the zygote should only contain 46 chromosomes 23 of these will be from the sperm cell and 23 from that egg if a reproductive cell has too many or too few chromosomes it could result in a genetic disorder. If gametes have diploid number(46) instead of haploid(23),then after each generation chromosome number in offspring will double ie 46+46=92 ,which will cause different problems and individuals will not survive.

Why is it necessary to reduce the chromosome number of gametes but not other cells of an organism german biologist oscar hertwig it was described again in 1883, at the level of chromosomes, by the belgian zoologist edouard van beneden, in ascaris worms' eggs. Uncategorized no comments why is it necessary to reduce the chromosome number of gamet why is it necessary to reduce the chromosome number of gametes (egg and sperm), but not other cells. 1 why is it necessary to reduce the chromosome number of gametes, but not other cells of an organism 2 if humans have 46 chromosomes in each of their body cells, determine how many chromosomes you would expect to find in the following. So to summarize, in mitosis, the total number of chromosomes is unchanged in the daughter cells whereas in meiosis, the total number of chromosomes is halved in the daughter cells let me know if you were looking for any other kind of information i'll update that in this answer.

Why is it necessary to reduce the chromosome number of gametes but not other cells of an organism

Human cells have 23 pairs of chromosomes (for a total of 46 chromosomes in all) most cells undergo cell division via mitosis, thus producing 46 2 = 92 chromosomes that are then split between the. So the cell can lower it's volume. Chromosome number, precise number of chromosomes typical for a given species in any given asexually reproducing species, the chromosome number is always the same in sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.

Gametes, on the other hand, are involved directly in the reproductive cycle and are most often haploid, meaning they only have one set of chromosomes allowing each contributing cell to pass on half of the needed complete set of chromosomes for reproduction. Why is it necessary to reduce the chromosome number of gametes, but not other cells of an organism 8 if humans have 46 chromosomes in each of their body cells, determine how many chromosomes you would expect to find in the following. In most animals, the haploid number (n) is unique to gametes (sperm or egg cells), and refers to the total number of chromosomes found in a gamete, which under normal conditions is half the total number of chromosomes in a somatic cell.

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. Mitosis: 1 division, creates 2 cells identical to the original (parent) cell with 46 chromosomes in humans, creates body (somatic) cells meiosis: 2 divisions, creates 4 cells with half the genetic information as the original (parent) cell with 23 chromosomes, creates reproductive cells (gametes: egg & sperm.
