Immunity may be defined as the body's ability to produce cells that inactivate foreign cells or substances.

<h3>What is the significance of best immunity?</h3>

The significance of the best immunity shields us by first constructing a barrier that prevents those invaders, or antigens, from entering the body.

The body's ability to produce the "fight or flight" response is stimulated by the sympathetic nervous system.  The body's ability to regulate homeostasis through feedback loops by maintaining the process of homeostasis.

Therefore, immunity may be defined as the body's ability to produce cells that inactivate foreign cells or substances.

PKU (Phenylketonuria) is an autosomal recessive disease, in which the synthesis of amino acid Tyrosine from Phenylalanine is blo
prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42
