Question
Holoblastic cleavage occurs in eggs containing which of the following?
- Yolk-rich
- Moderate to little yolk
- No yolk
Solution
Answer:
Holoblastic cleavage occurs in eggs containing moderate to little yolk.
Explanation:
Holoblastic cleavage refers to the type of cleavage where the entire egg is divided into smaller cells, or blastomeres. This type of cleavage is typical in eggs with a moderate amount of yolk or no yolk, allowing for complete division of the egg. In contrast, yolk-rich eggs exhibit meroblastic cleavage, where only a portion of the egg divides due to the presence of considerable yolk that impedes complete separation. Therefore, the correct option is "moderate to little yolk."
