Answer:
The correct answer is : The cerebellum.
Explanation:
The cerebellum is located under the cerebrum at the back of the brain. It is the part of the central nervous system that receives the information from the sensory systems to the different parts of the brain and spinal cord.
The major function of the cerebellum is to maintain postures, regulates muscle movements and balance. Other role of the little brain is to control speech, coordination.
Thus, the correct answer is - the cerebellum.
The answer is crossing over. it occurs in only meiosis
In the study of Gigord and colleagues using Elderflower orchids, the allele frequencies of yellow and purple flowers varied such that when the yellow allele started to become rare, the reproductive success of purple flowers decreased and the reproductive success of yellow-flowered individuals increased in a process known as <u>frequency-dependent selection.</u>
<u></u>
Frequency-dependent selection is an evolutionary process in which the fitness of a phenotype or genotype is dependent on the frequency of that phenotype or genotype in a particular population.
- Positive frequency-dependent selection raises the fitness of a phenotype or genotype as it becomes more prevalent.
- In the case of negative frequency-dependent selection, the fitness of an increasingly prevalent phenotype or genotype diminishes.
In a broader sense, frequency-dependent selection involves biological interactions that make the fitness of an individual dependent on the frequencies of other genotypes or phenotypes within the population.
