I am certain that the difficulties of maintaining a long-term immune memory to influenza viruses are due to the Antigenic shift from zoonotic sources. 
The adaptive immune response is intiated when the DCs present viral antigens to the naive and memory T-lymphoctes. During an influenza infection, the antigens are acquired by the DCs through two different mechanism.

In a population of deer mice, the allele for white hair is recessive and the allele for brown hair is dominant. If the populatio
tigry1 [53]

Answer:

The frequency of recessive allele should be 0.30.

Explanation:

According to Hardy-Weinberg equilibrium, sum of both dominant allele frequency (p) and recessive allele frequency (q) should be equal to 1 (p+q = 1).

Brown hair = dominant (p)

white hair = recessive (q)

49% mice are brown hair

so dominant genotype frequency = 0.49

According to Hardy-Weinberg principle, square root of the genotype (homozygous) is equal to allele frequency.

√p =√0.49 = 0.70

The dominant allele frequency is 0.7

Now, by this value we can find the recessive allele frequency by

p + q = 1

1 - 0.7 = 0.3

So, the recessive allele (white hair mice) frequency is 0.30.
