How many cells get produced in meiosis?
To answer this question, let's take a look at meiosis as a whole. Meiosis I: 1 Mother cell (with DNA that has been replicated) splits into two daughter cells (each are 2n). Meiosis II: Each of those 2 daughter cells split into two gametes (which are 1n each). Therefore at the end of meiosis 2, one daughter cell splits into two haploid cells. Remember, the mother cell (at the beginning of meiosis I) ends up splitting into a tetrad of haploid cells (ie. Mother cell splits into four haploid cells by completion of meiosis)
Are gametes produced by meiosis or mitosis?
In animals, gametes are formed only through meiosis. Mitosis does not produce gametes. However, in autotrophs, spores composed of gametes go though mitosis to produce a gametophyte.
The final cells resulting from meiosis in either males or females are called?
The common term for such cells is Germ cells. Depending on the gender, the germ cells destined to form sperms or pollen grains are called microspore mother cells and those resulting in to the egg cells are called megaspore mother cells.
1 List five stages in sexual reproduction?
Gamete production: Formation of haploid gametes through meiosis. Fertilization: Fusion of gametes to form a zygote with a full set of chromosomes. Embryonic development: Growth and differentiation of the zygote into an embryo. Gestation: Nourishment and protection of the developing embryo or fetus within the mother's body. Birth: Expulsion of the offspring from the mother's body to start an independent life.
Why do gametes only have half the usual number of chromosomes?
the division of sex cells occur in a different way from the cells of the other body part....... they undergo reduction division and there are stages of it.. the gametes have half the number of chromosomes (haploid) so that on fertilization it forms a correct human cell for further division and formation of bolus
What are haploid cells that contain chromosomes that are passed on to you from your parents called?
Gametes are the haploid cells which fuse together at fertilisation to form a zygote. One gamete is passed from your father, the other from your mother.
Are gametes haploid offspring haploid or diploid?
Gametes are haploid cells produced by the process of meiosis. They unite during fertilization to form a diploid zygote, which divides to form the embryo, and is the first cell of the new offspring of the organisms that produced the gametes. For example, human females produce ova, the female gametes, and human males produce sperm cells, the male gametes. During fertilization, one ovum and one sperm cell unite to form a zygote which divides by mitotic cell division, forming the embryo. The baby that is produced is not considered an offspring of the gametes, but an offspring of the mother and father that produced it.

Are offspring of gametes haploid or diploid?
Gametes are haploid. When two gametes unite during fertilization, they form a diploid zygote, genetically unique from either parent, and the first cell of the offspring. The zygote is not really considered an offspring of the gametes, but of the parent organisms that produced the gametes. For example, a human zygote is the first cell of a human baby formed when a sperm from a male and an ovum from a female unite during fertilization. The zygote and subsequent baby are the offspring of the mother and father.
What is the process of pollen production?
Pollen is produced in the anthers of flowers through a process called microsporogenesis. It begins with the division of microspore mother cells, which then undergo meiosis to produce haploid microspores. These microspores further develop into pollen grains, which contain the male gametes necessary for plant reproduction.
Are gametes produced by meiosis or mitosis?
In animals, gametes are formed only through meiosis. Mitosis does not produce gametes. However, in autotrophs, spores composed of gametes go though mitosis to produce a gametophyte.
How are oogenesis and spermatogenesis similar?
Oogenesis is the formation of the ovum, and spermatogenesis is the formation of the sperm. These two processes are similar as they are both formed by meiosis, (reduction division). Meiosis is the process of cell division where one mother cell will create four daughter cells with half the amount of genetic information. Or in other words, oogenesis and spermatogenesis are creating gametes.
The final cells resulting from meiosis in either males or females are called?
The common term for such cells is Germ cells. Depending on the gender, the germ cells destined to form sperms or pollen grains are called microspore mother cells and those resulting in to the egg cells are called megaspore mother cells.

During meiosis what is the chromosomes relationship between mother and daughter cells?
During meiosis, the relationship between mother and daughter cells involves the process of chromosome reduction. In the mother cell, the number of chromosomes is diploid (2n), while in the daughter cells, the number of chromosomes becomes haploid (n) after meiosis is completed. This allows for the formation of gametes with half the number of chromosomes as the parent cell.
Is the definitive nucleus in plants haploid in number?
No. Haploid is a term used to describe the genetic makeup of an animal with only one set of sister chromosomes. Humans are diploid organisms, which means they have 46 chromosomes, two sets of 23 (one from mother, on from father). Plants (and fungi) however, have a different developmental pathway which in certain organisms can result in only one set of chromosomes, or haploid. The huge diversity of plants include haploid, diploid, and polyploid (many copies of each chromosome) species.
Are megaspores mother cells haploid?
no they are diploid
