Answer:
Diffusion is the movment of particles from an area of high concentration to a low concentration down a concentration gradient
Answer:
Red allele frequency will be highest in population II
Population III can undergo bottleneck effect
The frequency of the brown allele will least likely be altered in the population I
Explanation:
Population I -
Total population - 
Brown birds - 
Red birds - 
Population II
Total population - 
Brown birds - 
Red birds - 
Population III
Total population - 
Brown birds - 
Red birds - 
Frequency of red birds in population I

Frequency of red birds in population II

Frequency of red birds in population III

Red allele frequency will be highest in population II and it will be equal to
as compared to
in case of population I and III
Population III can undergo bottleneck effect because of smaller population size
The frequency of the brown allele will least likely be altered in the population that has highest brown individual , i.e population I
A genotype is the genetic coding of a trait, so it's a paired combination of genes. A genotype has two alleles, which can be dominate or recessive, but overall the answer should be <span>a paired combination of genes</span>
