They will spread to non-endemic regions, especially in highlands areas. This is attributed to global warming that is resulting in increased global temperatures. Mosquitoes were know to only be endemic to warm regions such as coastal strips. As once cooler regions begin to warm up, mosquitoes will spread to the areas. Malaria will thus be more prevalent.

3. In one population, 18 individuals have long hair and 182 individuals have short hair. It is known thatmating has been random
pishuonlain [190]

Answer: p (short hair) = 0.91 and q (long hair) = 0.09

Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.

For this question, short hair is allele L and long hair is allele l

So, the frequency of short hair is p and of long hair is q.

To calculate the frequencies:

Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)

p = 182/200 = 0.91

The same formula goes for the recessive allele, so:

q = 18/200 = 0.09

Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
