In humans, cells are usually diploid or haploid. Diploid cells are two complete sets of chromosomes. At fertilization, we usually receive one complete set of chromosomes from each parent. Most of our body is diploid. Haploid cells have one complete set of chromosomes. Sex cells (sperm and eggs) are usually haploid. When two haploid cells fertilize each other, the resulting diploid cell can grow into a normal diploid embryo and ultimately to a full grown adult.
Mitosis produces diploid cells and is called mitotic cell division. Meiosis produces haploid cells and is called meiotic cell division. The stages that describe the process of cell division are the same in both mitosis and meiosis. They are Prophase, Metaphase, Anaphase and Telophase. Mitosis and meiosis are part of a larger process called the cell cycle. The stage interphase is part of the cell cycle, but not part of either mitosis or meiosis.
Meiosis consists of two rounds of cell division. The stages are distinguished from each other by using the Roman numerals I and II after the stage name, as in Metaphase I and Metaphase II. One full round of meiosis is Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and finally Telophase II.
Meiosis I the cell division that moves the cells from diploid to haploid. The exact stage of Meiosis I that moves the cell from diploid to haploid can be debated. Prophase I and Metaphase I are not options because the chromosomes have not really started to separate yet.
Anaphase I is the first realistic answer because the chromosomes begin to separate.
Telophase I shows the chromosome completely separated but the cell has not yet become two cells. The nuclei divide during a process called karyokinesis. The newly formed nuclei are in essence haploid, but the original cell is still intact and still has two full sets of chromosomes - albeit the sets are residing in different areas of the same cell.
The cell divides into two cells shortly after Telophase I. Thi is called cytokinesis. At this point the new cells are certainly haploid.
So the short answer is most definitely either anaphase I or telophase I. The stage that you choose will depend on the standards you use. Anaphase I will be the earliest by looking only at the nuclei. Telophase I will be the latest by looking only at the nuclei. Cytokinesis after Telophase I will be the latest.
I am assuming that this is a question for a Biology class. The key is to understand the difference between diploid and haploid and HOW they come about. Answering either Anaphase I or Telophase I should work IF you are able to support your answer by describing the process of Meiosis accurately.

Which life cycle stage is found in plants but not animals?
The alternation of generations is a life cycle stage found in plants but not in animals. This stage involves a switch between a multicellular haploid stage (gametophyte) and a multicellular diploid stage (sporophyte) in the plant life cycle.
Which term describes the multicellular haploid form of a protist that shows alternation of generations?
The multicellular haploid form of a protist that shows alternation of generations is referred to as the gametophyte stage. In this stage, the organism produces gametes (haploid reproductive cells) that fuse to form a zygote, which then gives rise to the sporophyte stage.
What is the name of the haploid form in plants?
The name of the haploid form in plants is gametophyte. It is the stage in the plant life cycle where the organism is haploid and produces gametes through mitosis.
In animals which stage is more dominant haploid or diploid?
In most animals, the diploid stage is more dominant than the haploid stage. This means that the majority of an animal's life cycle is spent in the diploid stage, where most body cells are diploid and capable of reproduction. The haploid stage, typically represented by gametes (sperm and egg cells), is usually a brief phase dedicated to sexual reproduction.
What is the difference between spermatogensis and oogensis?
Spermatogenesis is the process by which sperm cells are produced in the testes of males, while oogenesis is the process by which egg cells are produced in the ovaries of females. Spermatogenesis results in the production of four haploid sperm cells, while oogenesis produces one haploid egg cell and polar bodies. Additionally, spermatogenesis begins at puberty and continues throughout a male's life, while oogenesis begins before birth and has a limited number of egg cells that are released during a female's reproductive years.
What is a product of spermatogenesis?
formation of haploid spermatozoa
The process by which the seminiferous tubeles produce haploid sperm is called?
Spermatogenesis is the process by which the seminiferous tubules in the testes produce haploid sperm cells. This process involves multiple steps, including mitosis, meiosis, and spermiogenesis, leading to the formation of mature spermatozoa.
What is gametogenesis called in males?
Gametogenesis in males is called spermatogenesis. During this process, diploid cells called spermatogonia undergo mitosis and differentiation to form haploid sperm cells.
What does Gametogenesis in male animals results in?
Gametogenesis in male animals results in the production of the haploid sperm. This is called spermatogenesis.
What term best describes the cells in the gametophyte stage?
Haploid
Does spermatogenesis involves mitosis and meiosis?
There a number of steps involved in spermatogenesis process. The first one mitosis then the second stage is meiosis 1 followed by meiosis 2 and then spemiogenesis and finally the spermiation stage.
What is the dominant stage of liverworts?
The answer is gametophyte.
Which life cycle stage is found in plants but not animals?
The alternation of generations is a life cycle stage found in plants but not in animals. This stage involves a switch between a multicellular haploid stage (gametophyte) and a multicellular diploid stage (sporophyte) in the plant life cycle.
In moss the green leafy stuff is haploid or dipliod?
In moss, the green leafy stuff is haploid. Mosses have a life cycle that alternates between a haploid gametophyte stage (the leafy green structure) and a diploid sporophyte stage.
What does gametogenesis in male animals result in?
Spermatogenesis is the process of making more spermatozoa.
What does gametophyte dominated mean?
Plants have an alternation of generations when they are in the gametophyte stage or the sporophyte stage. Gametes, which is haploid, or spores, which are diploid. Seedless vascular plants can be dominated by a haploid gametophyte stage where they are most of the time.
The lifecycle of plants alternates between?
a haploid gametophyte stage and a diploid sporophyte stage..
