In humans, the male gamete is called sperm, and the female gamete is called an egg. When the gametes join they form a cell called a zygote.
In human fertilization, two 1n haploid cells—an ovum (female gamete) and a sperm cell (male gamete)—combine to form a single 2n diploid cell called the zygote. In fungi, the sexual fusion of haploid cells is called karyogamy. The result of karyogamy is a diploid cell called a zygote or zygospore. This cell may then enter meiosis or mitosis depending on the life cycle of the species. Haploid cells being produced via the process of meiosis. Note how each cell ends up having half the number of chromosomes as the parent cell. During the process of reproduction, haploid cells (male and female) unite to form a diploid zygote. There are two types of cells in the body-haploid cells and diploid cells. The difference between haploid and diploid cells is related to the number of chromosomes that the cell contains. The cells from each parent that combine to form the zygote are called gametes. In humans, the male gamete is called sperm, and the female gamete is called an egg. When the gametes join they form a cell called a zygote. The type of cell division that produces gametes with half the normal chromosome number is called meiosis. It is used to produce cells for repair and asexual reproduction. Gametes contain different genetic information to each other and to the parent cell. Meiosis is responsible for causing genetic variation. 1 During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. 2  Meiosis is the type of cell division that produces gametes. 3  It involves two cell divisions and produces four haploid cells. 1 Sexual reproduction involves two parents and produces offspring that are genetically unique. 2  During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. 3  Meiosis is the type of cell division that produces gametes. Meiosis produces haploid gametes with one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes. This same pattern, but not the same number of chromosomes, occurs in all organisms that utilize meiosis. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II. During the process of meiosis (cell division for sexual reproduction), the sex cells divide to produce gametes which then contain only one set of the chromosomes (n). When the male and female gametes fuse during fertilization and zygote formation, the chromosome number is restored to 2n again. Thus, diploid cells are those which contain a complete set (or 2n number) of chromosomes whereas haploid cells are those that have half the number of chromosomes (or n) in the nucleus. There are two types of cells in the body-haploid cells and diploid cells. The difference between haploid and diploid cells is related to the number of chromosomes that the cell contains. A zygote (from Greek ζυγωτός zygōtos joined or yoked, from ζυγοῦν zygoun to join or to yoke), is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual. In fungi, the sexual fusion of haploid cells is called karyogamy. The result of karyogamy is a diploid cell called a zygote or zygospore. This cell may then enter meiosis or mitosis depending on the life cycle of the species. Human zygotes contain 46 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is called meiosis. It is used to produce cells for repair and asexual reproduction. Gametes contain different genetic information to each other and to the parent cell. Meiosis is responsible for causing genetic variation. Is a cell that fuses with another cell during fertilization (conception) in organisms that reproduce sexually. Females produced a large gamete called an egg cell while males produce a tadpole-like gamete called a sperm cell. Zygote is the diploid cell that results from the fertilization between an egg and a sperm. Etymology. Came from the Greek word “gametes” meaning “husband” and “gamete” meaning “wife.”. Came from the Greek word “zygotos” meaning “joined or yoked or to yoke
