Crossing over takes place in ............ stage
-
Zygotene
-
Leptotene
-
Pacheytene
-
Diplotene
Correct Answer
A. PacheyteneExplanation
Crossing over, the exchange of genetic material between homologous chromosomes, takes place during the Pachytene stage of meiosis. This stage occurs after the Leptotene and Zygotene stages, where the chromosomes condense and pair up, respectively. In the Pachytene stage, the paired chromosomes undergo synapsis, forming structures called bivalents, and crossing over occurs within these bivalents. After Pachytene, the Diplotene stage follows, where the chromosomes begin to separate but remain connected at points of crossing over. Therefore, the correct answer is Pachytene.Rate this question:

How far apart should you space your plants?
-
6ft
-

-
2ft
-
As much space as needed
Correct Answer
A. As much space as neededExplanation
The answer "As much space as needed" is the most appropriate because the spacing between plants should be determined by the specific needs of each plant. Different plants have different requirements for sunlight, water, and nutrients, so it is important to provide enough space to accommodate these needs. Additionally, adequate spacing allows for proper air circulation, reducing the risk of diseases and pests. Therefore, the spacing between plants should be determined based on the individual requirements of each plant to ensure their healthy growth and development.Rate this question:
