Meiosis help (cells forming)?

Question

Why is it important that the four newly formed cells differ in chromosome info?
ty

Answer 1

Because this is one of the bases for variations resulting from sexual reproduction. No 2 gametes (in this case sperm cells) from an individual will be exactly alike genetically because of the random sorting during meiosis. The variation in the genetic makeup results in variations in offspring's. This is in most cases beneficial for species survival.

Answer 2

The four newly-formed cells are the gametes. The function of sexual reproduction is to increase the diversity of the population. The gametes should be different from each other (have variations) so that the resulting offspring will have variations. If a popuation has variation within it, then some members of the population may survive when others do not.

Answer 3

To keep one step ahead of our parasites allele frequency change; thus the combination of gametes should provide the necessary diversity. Google " The Red Queen " theory.

PS reproductive variation has nothing to do with " species survival ", except in the most incidental way.

Answer 4

the four new cells thus have novel combinations of chromosomes, and novel combinations of alleles on those chromosomes. this contributes to genetic diversity and increases the probability that an individual in the population will have some combination of genes that gives it a reproductive advantage and helps the species survive.

Answer 5

meiosis is meant for gamete productions... it produces sperms in men and egg cells in women persons and microspores n megaspores in flowers.... Meiosis Meiosis produces daughter cells that have one one million/2 the kind of chromosomes because of the fact the make certain cellular. 2N -------> N Meiosis facilitates organisms to reproduce sexually. Gametes (sperm and eggs) are haploid. Meiosis is mandatory in sexually-reproducing organisms because of the fact the fusion of two gametes (fertilization) doubles the kind of chromosomes. Meiosis is composed of two divisions generating an entire of four daughter cells. Meiosis contains 2 successive nuclear divisions with purely one around of DNA replication. 4 stages would nicely be defined for each nuclear branch. * Interphase: till now meiosis starts, genetic textile is duplicated. * First branch of meiosis o Prophase one million: Duplicated chromatin condenses. each and each chromosome incorporates 2, heavily linked sister chromatids. Crossing-over can ensue throughout the time of the latter area of this diploma. o Metaphase one million: Homologous chromosomes align on the equatorial plate. o Anaphase one million: Homologous pairs separate with sister chromatids ultimate jointly. o Telophase one million: 2 daughter cells are formed with each and each daughter containing purely one chromosome of the homologous pair. * 2nd branch of meiosis: Gamete formation o Prophase 2: DNA does not mirror. o Metaphase 2: Chromosomes align on the equatorial plate. o Anaphase 2: Centromeres divide and sister chromatids migrate one after the different to each and each pole. o Telophase 2: cellular branch is complete. 4 haploid daughter cells are obtained. One make certain cellular produces 4 daughter cells. Daughter cells have one million/2 the kind of chromosomes chanced on in the unique make certain cellular and with crossing over, are genetically diverse. Meiosis differs from mitosis widely speaking because of the fact there are 2 cellular divisions in meiosis, ensuing in cells with a haploid kind of chromosomes.
