Where does meiosis occur in animals and plants?
meiosis occurs in the sex cells of animals and plants. During meiosis, one of the cell’s pairs of chromosomes (the chromosomes that contain the genetic code of the species) splits and each half of the chromosome pairs becomes a new chromosome. This results in a reduction in chromosome number from the original “count” of chromosomes in the parents, which is a critical step in the development of sexual reproduction.
Where do meiosis occur in human beings?
In humans, meiosis occurs in the testicles and ovaries. During this process, the number of chromosomes in a normal human cell is halved. This is called “reduction division”. The end result is the creation of two genetically different daughter cells, each with a haploid number of chromosomes. This process is essential for sexual reproduction in humans and other species.
Where do meiosis occur in plants?
Plant meiosis occurs in the plant ovule. Like animal meiosis, plant meiosis is the reduction division of one cell to form two daughter cells. However, plant meiosis has three unique characteristics in addition to the two divisions that animal meiosis goes through. First, it consists of two separate divisions, the first of which produces four haploid nuclei, and the second of which merges the haploid nuclei to form a diploid. Second, the two meiotic divisions occur
Where do meiosis occur in animals?
In animals, meiosis occurs in the gonads. The testis produces sperm and the ovaries produce eggs. In humans, the testis is located in the scrotum and the ovaries are inside the uterus. In other animals, the testes and ovaries are located outside of the body, usually on the same organ. In plants, meiosis occurs in the ovule. The number of germ cells in an ovule determines the number of seeds that will be produced.
Where do meiosis occur in fish?
In most fish species, meiosis takes place in the gonadal tissue, a structure that is also called an ovary or testis. In many species, meiosis also occurs in the surrounding tissue, called the germinal or germline cells, which will later develop into eggs or sperm.
