Question
True or false: Patterns of cleavage of animal eggs is the same among all animal phyla.
True false question.
TrueFalse
Solution
Answer
False.
The patterns of cleavage in animal eggs exhibit significant variation among different animal phyla. For example, in mammals, cleavage is generally characterized by a holoblastic pattern, where the egg divides completely. In contrast, some other animals, like fish and reptiles, exhibit meroblastic cleavage, where only a part of the egg is divided due to the presence of a large yolk.
Additionally, different classes within phyla can display varying cleavage patterns. Thus, it is inaccurate to say that cleavage patterns are uniform across all animal phyla; they are influenced by factors such as the amount and distribution of yolk in the egg.
