After fertilization, the zygote undergoes rapid cell division through a process called cleavage. Initially, the number of cells doubles approximately every 24 hours during the first few days, resulting in a two-cell stage, then a four-cell stage, and so on. This rapid division continues until the embryo forms a blastocyst, typically around five to six days post-fertilization. However, the exact timing can vary based on species and specific conditions.
What else can I help you with?
Which has the greater number of cell zygote or morula?
the MORULA because it has already undergone cell division. Unlike the zygote which has 1 cell only
What is the order of fertilization sex cells meiosis zygote mitosis?
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.
Does a zygote have a haploid number of chromosomes?
A zygote is a fertilized egg, so half of the number came from the sperm (a haploid number or n) and half came from the egg (also a haploid number or n) so the zygote has a diploid chromosome number (2n).
What do the four daughter cells look like compared to the original zygote?
The four daughter cells resulting from meiosis are genetically unique and have half the number of chromosomes as the original zygote. They are also haploid, meaning they contain one set of chromosomes.
What is the process called that makes cells specialized?
zygote, stem cells, cell differentiation zygote, stem cells, cell differentiation

How does the number of chromosomes in a zygote compare with the number of chromosomes in a body cell?
A zygote typically has a full set of chromosomes, with one set from each parent, so it has a diploid number of chromosomes. In contrast, body cells are also diploid, containing the same number of chromosomes as the zygote.
Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
Does a zygote have a haploid number of chromosomes?

Which ohe following contains the greatest number of totipotent stem cells?
Totipotent stem cells are present in the earliest stages of embryonic development, specifically in the fertilized egg (zygote) and the first few divisions of the embryo. Therefore, the zygote contains the greatest number of totipotent stem cells. As development progresses, these cells differentiate into pluripotent and multipotent cells, losing their totipotency.
Specialized cells known as zygote cells are produced by the reproductive system?
Zygote cells are not produced by the reproductive system. Zygote cells are formed when an egg cell is fertilized by a sperm cell during the process of fertilization. Zygote cells contain the genetic material from both the egg and sperm and have the potential to develop into a new organism.
How many cells will there be after 8 successive mitotic divisions of a zygote?
After 8 successive mitotic divisions of a zygote, there will be 256 cells. Each mitotic division doubles the number of cells, so if the zygote starts with 1 cell, it will be divided into 2, then 4, then 8, and so on, until reaching 256 cells after 8 divisions.
What is the Term meaning single cells formed immediately after conception?
The term for single cells formed immediately after conception is "zygote."
When the sperm cells joins an egg cells what is formed?
zygote
