Question:
Given below are two statements about embryonic development in human.
Statement (I): There is no growth phase between cleavages and the size of blastomeres is reduced.
Statement (II): As the size is reduced, the subsequent cleavages are faster than earlier ones.
In light of the above statements, choose the most appropriate answer from the options given below.

Statement (II): As the size is reduced, the subsequent cleavages are faster than earlier ones.
In light of the above statements, choose the most appropriate answer from the options given below.
Show Hint
Cleavage has no growth phase so blastomeres get smaller, but human cleavage is slow, not progressively faster.

- Both Statement (I) and Statement (II) are correct.
- Both Statement (I) and Statement (II) are incorrect.
- Statement (I) is correct but Statement (II) is incorrect.
- Statement (I) is incorrect but Statement (II) is correct.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Cleavage is the series of mitotic divisions of the zygote that forms blastomeres.
Step 2: Check Statement I
There is no growth phase between cleavages, so the zygote's volume is divided and blastomeres become smaller. Statement I is correct.
Step 3: Check Statement II
Smaller cells do not make later divisions faster. Human cleavage is slow and asynchronous. Statement II is incorrect.
Final Answer:
Statement I is correct but Statement II is incorrect. \[ \boxed{\text{(C) }\text{Statement (I) is correct but Statement (II) is incorrect.}} \]
