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

The zygote could not develop into a person so, instead, the man and woman have to only put half the number of chromosomes into each gamete that means that the sperm would get 23 chromosomes, the egg would get 23 chromosomes, and the zygote would end up with the correct number of chromosomes, 46, after fertilization. Most cells undergo cell division via mitosis, thus producing 46 2 = 92 chromosomes that are then split between the two new cells to give each one 46 chromosomes (as 23 pairs) so mitosis takes one diploid cell and produces two diploid cells with the proper number of chromosomes for a human cell. 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 two new cells to give each one 46 chromosomes (as 23 pairs.

So mitosis takes one diploid cell and produces two diploid cells with the proper number of chromosomes for a human cell gametes, or sex cells, are unique in human cells have 23 pairs of chromosomes (for a total of 46 chromosomes in all. 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.

What is the state of the dna at the end of meiosis i what about at the end of meiosis ii 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,.

The first phase has 46 chromosomes (2 cells created) and the second phase has 23 chromosomes (4 cells created) meiosis only occurs in gametes (or sex cells) the reason why the number of chromosomes reduces is because the offspring must have 46 chromosomes. Experiment 4 exercise 2 meiosis review this weeks reading in your book pp 131 from bi 101 at park university why is it necessary to reduce the chromosome number in gamete cells (egg and sperm), 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 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 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.

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 17 blue whales have 44 chromosomes in every cell. Start studying this meiosis learn vocabulary, terms, and more with flashcards, games, and other study tools why is it important that gametes have half as many chromosomes as somatic cells meiosis must reduce the number of chromosomes so that fertilization can restore the diploid number to prevent to many chromosomes.

  • Gametes contain half of the number of chromosomes as somatic cells (the other cells of your body) these chromosomes have the same number of alleles on them as somatic cells, but gametes contain one allele of each gene while somatic cells contain two alleles of each gene.
  • Meiosis 1 occurs by producing genetic recombination in the daughter cells while in meiosis 2 each of the four daughter cells will contain half the amount of chromosomes of the parent cell another difference is that meiosis 1 has five phases prophase 1, metaphase 1.

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. Meiosis is a reduction division that is necessary in sexually reproducing organisms to maintain the species number of chromosomes gametes, or sex cells must have half the chromosomes that the parent cell has at fertilization, two gametes fuse together to form the offspring. 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. Meiosis meiosis is the process in which gametes are produced in meiosis, 4 haploid (think haploid- half) daughter cells are produced from the parent cell these cells have half the number of chromosomes as the parent cell for example, normal human cells have 46 chromosomes, where gametes have only 23.
