An MRI takes pictures of basic brain structures. ï· In early Parkinsonâs disease (PD), MRI of the brain is usually normal so researchers use it to check to be sure there is no other neurological reason for a patientâs PD symptoms.
Gametes are produced by a type of cell division called meiosis. They are haploid, meaning that they 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 zygote is diploid and contains two sets of chromosomes.efinition: Gametes are reproductive cells (sex cells) that unite during sexual reproduction to form a new cell called a zygote. Male gametes are sperm and female gametes are ova (eggs). In seed bearing plants, p ollen is the male sperm producing gametophyte. Female gametes are contained within the plant ovary.
A Zygote is the cell formed when two gamete (or sex cells) are joined by sexual reproduction. The zygote develops into the baby. The zygote is only the initial stage of the â¦ development of the offspring. Usually, a zygote if formed by an ovum and sperm. The ovum being the female sex cell and the sperm being the male's. zygote is the initial cell developed through sexual reproduction and formed when two gametes come together. In other words, a zygote results when the female egg is fertilize â¦ d. After rapid cell division, it eventually becomes an embryo. 20 people found this useful.
