what is the relationship between haploid diploid and zygote

If the diploid number in a liver cell is 52, how many chromosomes are there in the egg of this . What is the difference between a haploid, diploid, and zygote?. Cells starting mitosis & meiosis begin with a (haploid or diploid) set of chromosomes. diploid. 7. What is the difference between a haploid, diploid, and zygote?. Diploid cells contain a full set of chromosomes for a specific species (ie. Originally Answered: What's the difference between diploid and haploid? . the resulting cell ("zygote") has 46 chromosomes (23 pairs) and is ready to start becoming.

In these species, gametes must be contributed by two individuals of different sexes. However, some animal species are hermaphroditic, meaning that they have both male and female reproductive organs and can make both types of gametes. Simultaneous hermaphrodites organisms that have both male and female reproductive organs at the same time may be able to self-fertilize, providing both sperm and egg to make a zygote.

Example of a diploid-dominant life cycle: In a mature human 2neggs are produced by meiosis in the ovary of a woman, or sperm are produced by meiosis in the testis of a man.

The eggs and sperm are 1n, and they combine in fertilization to form a zygote 2n. The zygote divides by mitosis to produce a mature human.

Fertilization terminology: gametes, zygotes, haploid, diploid

Image modified from " Sexual reproduction: An example of a fungus with a haploid-dominant life cycle is black bread mold, whose sexual life cycle is shown in the diagram below. In sexual reproduction of this mold, hyphae multicellular, thread-like haploid structures from two compatible individuals first grow towards each other. Where the hyphae meet, they form a structure called the zygosporangium.

A zygosporangium contains multiple haploid nuclei from the two parents within a single cell.

The haploid nuclei fuse to form diploid nuclei, which are equivalent to zygotes. The cell containing the nuclei is called the zygospore. Example of a haploid-dominant life cycle: A haploid spore 1n undergoes mitosis to produce a multicellular individual 1n with thread-like structures called hyphae.

Nuclear fusion then takes place, in which the haploid nuclei fuse to form diploid nuclei, and the cell containing the diploid nuclei is called the zygospore. The diploid nuclei in the zygospore undergo meiosis to produce haploid nuclei, which are released as unicellular spores 1nand the cycle repeats. Because they were formed through meiosis, each spore has a unique combination of genetic material.

The spores germinate and divide by mitosis to make new, multicellular haploid fungi. Alternation of generations The third type of life cycle, alternation of generations, is a blend of the haploid-dominant and diploid-dominant extremes.

This life cycle is found in some algae and all plants. Species with alternation of generations have both haploid and diploid multicellular stages.

The haploid multicellular plants or algae are called gametophytes, because they make gametes using specialized cells. Meiosis is not directly involved in making the gametes in this case, because the organism is already a haploid. Fertilization between the haploid gametes forms a diploid zygote. The zygote will undergo many rounds of mitosis and give rise to a diploid multicellular plant called a sporophyte.

Specialized cells of the sporophyte will undergo meiosis and produce haploid spores. Become a Contributor Diploid and Haploid Cells Diploid and haploid cells are involved in sexual reproduction of higher eukaryotic organisms.

The following BiologyWise article will cover some information related to the diploid and haploid cells. BiologyWise Staff In a biological cell, the number of complete chromosomal sets is called ploidy. The somatic cells of the human body are diploid in humans.

However, the sex cells, that is, sperms and egg are haploid. In certain plants, amphibians, reptiles, and insect species, one may see tertaploidy four set of chromosomes.

So what are these diploid and haploid cells? If you are searching for answers to these questions, then the following paragraphs will help answer your queries. What are Diploid and Haploid Cells?

The sex cells or gametes contain haploid cells which means that these cells have one set of chromosomes, that is, 23 chromosomes. So there's two to three hundred million of these characters and they're all vying for this ovum and the one that you see that's about to fuse for it, this is the winner of this incredibly - remember two to three hundred, million to million sperm are trying to get here so this is a major victory and to some degree we should all feel pretty good about ourselves because we are all the by-product of that one in to million sperm cells that won this race getting to our mother's ovum.

So the sperm cell came from our father and the egg cell, this is all happening inside of our mothers, the egg cell is from our mother.

Now, once this happens, let's talk a little bit about the terminology. So once these two fuse, or the process of them fusing, we call that fertilization. And it produces a cell that then differentiates into all of the cells of our body, so you can imagine that this is an important process.

So let's make sure that we understand the different terminology, the different words for the different things that are acting in this process. So each of these sex cells, I guess we could say, the sperm cell and the ovum, these are each called gametes. So this right over here is a gamete and the ovum is a gamete, the egg cell is also a gamete. And as we'll see, each gamete has half the number of chromosomes as your body cells or most of the somatic cells of your body so outside of your sex cells that might be in your ovaries or your testes, depending on whether you're male or female, these have half the number so let's dig a little bit deeper into what I mean there.

So let's just do a blow up of this sperm cell right over here, so a blow up of a sperm cell and I'm not going to draw it to scale, you see the sperm cell is much smaller than the egg cell but just to get a sense, so let me draw the nucleus of this sperm cell, so just like that.

If we're talking about a human being, and I'm assuming you are a human being, so that might be of interest to you, this will have 23 chromosomes from your father so let's do them. One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 and for the 23rd one, that's going to be your sex-determining chromosome so if your father contributes an x, you are going to be female, if your father contributes a y, you are going to be male.

So these are the chromosomes in the male gamete or I guess I should say the gamete that your father's contributing, the sperm. So this is a gamete right over here and that's going to fuse with the egg, the ovum that your mother is contributing and once again, I'm not drawing that to scale.
