What is a gamete apex?
gamete. A sex cell in the male or female, with half the genetic material of other cells.
Which is best described as gamete?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These cells develop into sperm or ova. …
What is a gamete Brainly apex?
A gamete is the male or female reproductive cell that contains half the genetic material of the organism.
What describes a Tetrad?
Definition of tetrad
: a group or arrangement of four: such as. a : a group of four cells produced by the successive divisions of a mother cell a tetrad of spores. b : a group of four synapsed chromatids that become visibly evident in the pachytene stage of meiotic prophase.
Is gametes mitosis or meiosis?
Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. The single zygote cell never grows or divides my mitosis. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.
What is gamete formation answer in one sentence?
Gametes are formed through a process of cell division called meiosis. This two-step division process produces four haploid daughter cells. Haploid cells contain only one set of chromosomes. When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote.
What is the product of meiosis 1 apex?
Meiosis one results in 2 haploid cells (duplicated), meanwhile meiosis two results in 4 haploid cells that are not doubled.
What is the product of meiosis II apex?
The product of meiosis II is four haploid gamete cells. Gametes are sex cells, used in the reproductive process, and haploid means that they have half…
What happens in meiosis during telophase 1 apex?
When the meiotic cycle gets to Telophase I , the parent cell has two poles, each with a complete haploid set of chromosomes (which still have their sister chromatids). At this moment, a cleavage furrow is formed, dividing the cell’s cytoplasm in half (a proccess ultimately called cytokinesis).
How is meiosis different from mitosis apex?
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
What is a tetrad in mitosis?
A tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
What cells are a product of meiosis?
Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.
What type of cells are diploid?
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.
