What types of cell divisions are involved in creating a puppy?
The creation of a puppy involves mitotic cell division for growth and development, meiotic cell division for the formation of gametes (sperm and egg), and fertilization of the egg by the sperm to form a zygote that will develop into a puppy.
How would you distinguish human mitotic cells from human meiotic cells?
Human mitotic cells undergo cell division to produce two identical daughter cells with the same number of chromosomes as the parent cell. In contrast, human meiotic cells undergo two rounds of cell division to produce four haploid daughter cells with half the number of chromosomes as the parent cell. Meiotic cells are involved in the formation of gametes (sperm and egg cells) for sexual reproduction, while mitotic cells are involved in growth, repair, and asexual reproduction.
In which types of cells does mitosis not occur?
Mitosis does not occur in sex cells, such as sperm and egg cells, as they undergo a different type of cell division called meiosis.
What type of cell division occurs in cloning?
Cloning typically involves somatic cell nuclear transfer, where the nucleus of a somatic cell is transferred into an enucleated egg cell. This process leads to the creation of a genetically identical organism to the original donor.
What happens when a fertillized egg splits?
The fertilized egg is in the eggshell. It is an extremely large egg. It fills the egg shell. It is larger than the chick will be when it hatches! It divides like any other cell and becomes smaller.
When does fertilization in mitosis occur?
Fertilization in mitosis occurs when the sperm and egg cells fuse during sexual reproduction, typically in the reproductive organs of plants and animals. This fusion of gametes results in the formation of a zygote, which then undergoes mitotic cell division to develop into a new organism.
What is the order of these mitotic stages?
1.) fertilization of egg by sperm 2.) mitotic cell division of zygote 3.) differentiation of cells into tissues 4.) organ development

Where do mutations takes place?
They occur during cell division and at the time when the sperm fertilizes the egg.

Where does mitosis occur in zygotic life cycle?
Mitosis occurs during the zygotic life cycle in the zygote stage. After the fertilization of egg by sperm, the zygote divides through mitosis to give rise to a multicellular embryo. This process of mitotic division continues to generate all the cells of the developing organism.
In which types of cells does mitosis not occur?
Mitosis does not occur in sex cells, such as sperm and egg cells, as they undergo a different type of cell division called meiosis.
The cloning of cells involves in the process of?
The cloning of cells involves the production of genetically identical copies of a cell through a process called somatic cell nuclear transfer (SCNT). In SCNT, the nucleus of a somatic cell is inserted into an egg cell that has had its nucleus removed. This new cell then divides and develops into an identical copy of the original cell.

Do flowers reproduce through mitosis?
Flowering plants can reproduce through mitotic cell division, or asexual reproduction. However, the flowers are the sexual reproductive organs, producing egg cells and sperm cells. Egg cells are found in the ovary of a flower, and the sperm cells are found in the pollen. Therefore, flowering plants also undergo sexual reproduction when a sperm cell reaches an egg cell.
Where in the body does meiosis occur?
Meiosis is cell division of the germ cells, the egg and sperm. It occurs in the ovary in females and testis in males.
