meiosis starts off with interphase where it is a normal double chromosomed (chromatid because it is still loose and not in chromosome form yet) thingy. Then prophase I occurs which causes the chromosome to make rods of DNA called chromosomes, but these chromosomes are double homologous chromosomes because the DNA has been copied during the S phase of interphase (still diploid at this point). Then after metaphase, anaphase, and telophase, 2 new cells start forming and we know that metaphase, anaphase, and telophase split the double homologous chromosomes, so then the new cells still have double chromosomes (haploid but there are 2 copies of each chromosome), and another round of meiosis occurs (meiosis II) which splits the double chromosomes into just normal halpoid gametes.
All this is in accordance to humans
Oocyte
Yes, polar bodies are haploid cells. They are produced during oogenesis when the cytoplasm of the primary oocyte is unequally divided during meiosis, resulting in one large secondary oocyte and two smaller polar bodies.
Meiosis II is completed after entry of sperm.
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
Oocyte
gametes, sex cells, haploid cells. the process is meiosis.
Unfertilized egg is haploid; but fertilized egg is diploid. That is why you sometimes see chickens even in commercial eggs.
Yes, polar bodies are haploid cells. They are produced during oogenesis when the cytoplasm of the primary oocyte is unequally divided during meiosis, resulting in one large secondary oocyte and two smaller polar bodies.
Depends. In males all four cells become sperm. In females one becomes to oocyte while the other three become polar bodies that can provide some nutrients to the oocyte, or just dissipate depending on species.
ploidy is the classification based on the number of homologous chromosomes present. if there is only one pair of homologous chromosomes then the nucleus is said to be haploid if there are two pairs then it is known as diploid if three it is triploid if many it is noted as polyploidy --------------------------- an oocyte or a spermatocyte are haploid cells in a species that normally have diploid cells.
Meiosis II is completed after entry of sperm.
An egg cell is haploid.
The haploid cells are the sperm and egg cell.
Yessiree!
