is a zygote a haploid?

"Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.

Zygotes are cells produced as a result of sexual reproduction when male and female gametes are fused for fertilization to take place. Zoospores, on the other hand are the asexually reproductive structures generated by some algal and fungi species to reproduce.

They differ in having the number of chromosomal sets. Gametes have the haploid number of chromosomes as the one gamete is able to fuse with another one to form a diploid cell which is the zygote. Somatic cells re diploid cell having two full sets of chromosomes.

When an egg or sperm that has undergone faulty meiosis and has an abnormal number of chromosomes unites with a normal egg or sperm during conception, the zygote formed will have an abnormal number of chromosomes, a condition called aneuploidy, which has several types of expression: If the zygote has an extra chromosome ...

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.

The male and female gametes fuse to form the zygote. Due to the fusion of gametes the product of sexual reproduction generally generates new genetic combinations leading to variations. The organism develops from the zygote which has characters of both the parents.

The zygote contains all of the genetic information (DNA) needed to become a baby. Half the DNA comes from the mother's egg and half from the father's sperm.

Double Fertilization: 1. It is union of one male gamete with egg and the other male gamete with secondary nucleus of the same embryo sac. ... Double fertilization produces a diploid zygote and a triploid primary endosperm cell.

Zygote is the initial single celled fertilized egg. As it develops differentiated cell layers appear (ecto, meso, and endoderm) in what is now called the embryo.

In single-celled organisms, the zygote becomes a fully functioning organism, and can divide through mitosis to produce offspring. The organism can also produce gametes to reproduce sexually with other cells.

A zygote is the union of the sperm cell and the egg cell. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo.
82968
During sexual reproduction, fertilization of the ovum (n, 23 chromosomes) by the sperm (n, 23 chromosomes) restores the diploid number and creates a zygote (2n, 46) that divides and grows by mitosis to form a multicellular human.

Zygotes and Blastocysts. The fertilized egg, which is diploid, that results from the union of the sperm cell nucleus and an egg cell nucleus is called a zygote. ... After about one week, a single-cell zygote developes into a multi-celled blastocyst.

Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Stages of human development Zygotic stage: The zygote is formed when the male gamete (sperm) and female gamete (egg) fuse. Blastocyst stage: The single-celled zygote begins to divide into a solid ball of cells. Then, it becomes a hollow ball of cells called a blastocyst, attaching to the lining of the mother's uterus.

A zygote is the sperm and the egg after they have combined, therefor a zygote has two nuclei.

"Zygote: This cell results from the union of an oocyte and a sperm. A zygote is the beginning of a new human being (i.e., an embryo). The expression fertilized ovum refers to a secondary oocyte that is impregnated by a sperm; when fertilization is complete, the oocyte becomes a zygote."10 (Emphasis added.)
