When does an oocyte become a haploid cell?

Answer 1

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

Answer 2

When one of the daughters of the primary oocyte, aka one of the seconday oocytes goes through the second meiotic division. One of those daughter cells forms a haploid ootid that eventually turns into a mature ovum. ( the other forms a polar body)

This second meiotic division is not completed until fertilization in some species, such as humans.

Answer 3

An oocyte becomes a haploid cell during the process of meiosis. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid cells. In females, meiosis is completed in the oocyte during ovulation.

Answer 4

In meiosis cells become haploid in telophase I.

Answer 5

The property of cell to change from diploid to haploid is only in heterosomal or sex cell. When the sperm or ovum cell generated it originate by forming haploid from diploid

Answer 6

The only haploid cells are the reproductive cells, i.e. the sperm and egg.

Answer 7

Haploid cells become diploid cells when fertilization occurs during sexual reproduction. This involves the joining of two haploid cells, which become a diploid cell.
