The process which gametes from two parents combine to from one new cell?

In sexual reproduction, genetic material from two separate organisms is combined in the offspring. The other alternative is asexual reproduction, in which the genetic material for the offspring comes from just one parent.

∙ 14y agoThe production of gametes is termed gametogenesis. In diploid organisms, it is a process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes or by mitotic division of haploid gametogenous cells. For example, in vertebrates, meiosis in diploid organisms reduces the number of sets of chromosomes from two to one (i.e., produces haploid gametes from diploid gametocytes). On the other hand, plants may produce gametes through mitosis in gametophytes. The gametophytes grow from haploid spores after sporic meiosis. The existence of a multicellular, haploid phase in the life cycle between meiosis and gametogenesis is also referred to as alternation of generations. Organs that produce gametes are called gonads in animals, and archegonia or antheridia in plants.

Does every cell have genetic material?
No, the gametes or sex cells contain only half of the chromosomes of a body cell so the gene count would not be equal.
How could cloning help infertile couples have children?
Cloning can help infertile couples to have 'children' but as kid-twin of the mother or the father. Children would be genetically brother or sister of the either parents. P.S. - Cloning needs somatic (body) cell chromosome unlike in natural births (requiring gametes - reproductive cells).
Does cossing over lead to genetic variation?
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
What is molecular cloning?
cellular cloning is the process of making a populaion of cells from a single cell. cellular cloning is the process of making a populaion of cells from a single cell. cellular cloning is the process of making a populaion of cells from a single cell.
How is genetic information passed down from one generation to the next in plants?
Genetic information in plants is passed on from one generation to the next just like in any other living organisms. This is through genes. Genes are parts of the chromosomes whose greater part is the DNA. Through the process of meiosis (which is cell division) the number of chromosomes in a cell is halved. this leads to gametegenesis which is the formation of gametes. each resulting cell with half the number of chromosomes as the original cell carries all the genes.
Why do gametes need 12 the number of chromosomes of a regular body cell?
Gametes require half the number of chromosomes of a somatic (regular) cell as gametes are the sex cells. When gametes combine to make a zygote (a fertilised cell), the complete number of chromosomes will be present.
What is the process of making gametes called?
Male gametes* --->Meiosis. (basic pre-biology in most all biology books)
What is another name for an immature egg cell?
gametes, sex cells, haploid cells. the process is meiosis.
The process of cell division that forms incomplete cells or gametes is called?
meiosis
What age does baby estabilish eye color?
The moment the Gametes combine and a somatic cell is formed, in simpler words the moment the egg combines with the sperm and the chromosomes combine.
How do gamates go to the over to offspring?
Gametes are individual DNA strands that all have a pair. In a human, the male has 23 in each sperm cell, and the woman has 23 in each egg cell. When the sperm and egg cell combine, the gametes combine and form matching pairs (not genetically identical) and then a zygote forms. The gametes are what makes up the genetical information of the zygote, which will eventualy grow inot a newborn. These gametes confirm what gender the baby will be, what they will look like ect. These gametes can also pass on disease - for example, a gamete with a mutation that causes down's syndrome.
What the process of egg cell and sperm cell?
The process when an egg cell and a sperm cell COMBINE is called Fertilization
What are the different types of sex cells?
The human gametes are the sperm cell (male) and the egg cell (female). The chromosomes carried by the sperm cell can have two forms, the X cell (female offspring) or the Y cell (male offspring). These combine with the egg cell, which virtually always carries only an X chromosome. So an XX cell would develop as a female, and an XY cell would result in a male offspring.
What cell process creates sex cells?
Its made from the Meiosis
Which cell division process is used in the production of gametes during Mitosis or Meiosis?
Meiosis
What type of cells are produced after fertilization occurs and the gametes combine?
The cell created by fertilisation is called a zygote.
Cells that contain half the usual number of chromosomes are?
A sperm cell and an egg cell. They combine to make a baby with full chromosomes.
