The correct Answer is:
To solve the question regarding macrolecithal eggs, we can break it down step by step: ### Step-by-Step Solution: 1. **Understanding the Term "Macrolecithal":** - The term "macrolecithal" refers to a type of egg that contains a large amount of yolk. The prefix "macro-" indicates "large," while "lecithal" relates to yolk. 2. **Analyzing the Options:** - **(a) Little yolk:** This option suggests that macrolecithal eggs have a small amount of yolk, which contradicts the definition of macrolecithal. - **(b) Abundant yolk:** This option aligns with the definition of macrolecithal eggs, as they are characterized by having a large amount of yolk. - **(c) Entry of sperm:** While the entry of sperm is a crucial part of fertilization, it does not specifically characterize macrolecithal eggs. - **(d) Pattern of cleavage:** The pattern of cleavage can vary among different types of eggs, and while it may be influenced by the amount of yolk, it is not a defining characteristic of macrolecithal eggs. 3. **Conclusion:** - Based on the definitions and characteristics discussed, macrolecithal eggs are best characterized by having **abundant yolk**. Therefore, the correct answer is option **(b) Abundant yolk**. ### Final Answer: (b) Abundant yolk
