Download to view full explanation
Crop rotation is the agricultural process of planting different crops in the same fields in a specific order. This process is used to maintain soil fertility, prevent soil erosion, and control pests and diseases. By rotating crops, farmers can avoid depleting the soil of specific nutrients that are required by certain crops. For example, legumes such as beans and peas can fix nitrogen in the soil, which can be used by other crops such as corn or wheat. Crop rotation has been used for centuries and is an important practice in sustainable agriculture.

Question
Which of these is a type of
genetic drift?
Bottleneck effect
Natural selection
Answer

Bottleneck effect

Download to view full explanation
The bottleneck effect is a type of genetic drift that occurs when a population undergoes a drastic reduction in size due to a random event such as a natural disaster, disease outbreak, or human interference. This reduction in population size can lead to a loss of genetic diversity, as certain alleles may be lost or become more common due to chance. As a result, the genetic makeup of the population may be significantly different from the original population, and this can have long-term effects on the population's ability to adapt to changing environmental conditions.
