Which of the following statements is correct about reproduction? 1. Bulls alone can produce a calf. 2. Hens alone can not produce new chicks.
Analyzing Reproduction Statements
The question asks to evaluate two statements regarding animal reproduction.
Statement 1 Analysis: Bulls and Calves
Statement 1 claims: "Bulls alone can produce a calf."
Reproduction in cattle requires the involvement of both a male (bull) and a female (cow). A bull provides genetic material, but gestation and birth (producing a calf) require a cow. Therefore, a bull cannot produce a calf alone.
Conclusion: Statement 1 is false.
Statement 2 Analysis: Hens and Chicks
Statement 2 claims: "Hens alone can not produce new chicks."
Hens lay eggs. For these eggs to develop into new chicks, fertilization by a rooster (male chicken) is necessary. While a hen can lay unfertilized eggs, these will not hatch into chicks. Thus, a hen alone cannot produce new chicks.
Conclusion: Statement 2 is correct.
Final Conclusion
Based on the analysis:
- Statement 1 is false.
- Statement 2 is correct.
This corresponds to the option stating that Statement 2 is correct and Statement 1 is false.
