What phase of the cell does Cleavage begin?
it begins 36 hours after fertilization
How does the amount of yolk affect blastulation?
Yolk slows down cleavage. Those eggs that contain a lot of yolk in one end of the egg undergo meroblastic cleavage. Their blastulae contain both macromeres and micromeres.
Do all zygotes develop?
No.
What is silvers cleavage?
Silvers Cleavage Is Silver Doesn't Split .
What results in fertilization?
zygotes :)
What is the name of the two poles created as a result of holoblastic cleavage?
Hand Pole and Mouth PoleIn embryology, cleavage is the division of cells in the early embryo. The zygotes of many species undergo rapid cell cycles with no significant growth, producing a cluster of cells the same size as the original zygote. The different cells derived from cleavage are called blastomeres and form a compact mass called the morula. Cleavage ends with the formation of the blastula.Depending mostly on the amount of yolk in the egg, the cleavage can be holoblastic (total or entire cleavage) or meroblastic (partial cleavage). The pole of the egg with the highest concentration of yolk is referred to as the vegetal pole while the opposite is referred to as the animal pole.
When is a zygote called a fetus?
Embryo's are called fetuses after 8 weeks. The term zygotes is only used right after fertilization before cleavage occurs when the embryo is still a single cell.
