Cystic fibrosis is most common in individuals of Northern European descent, affecting 1 in 3200 newborns. Assuming that these al
IgorLugansk [536]

Answer:

0.0177

Explanation:

Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:

1/3200 = q² (have two CFTR mutant alleles) >>  

q = √ (1/3200) = 1/56.57 >>

- Frequency of the CFTR allele q = 1/56.57 = 0.0177  

- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823

A common mechanism of injury for an anterior tibiofibular ligament sprain is When icing an athlete with an ice bag and elastic w
Andrej [43]

Answer:

The correct answer will be

1. Inversion

2. 20-25 minutes

Explanation:

The injuries of the ligaments of the ankle are common among athletes like the anterior tibiofibular ligament sprain (AFTL) or calcaneofibular ligament (CFL) which are caused by the inversion of the flexed foot.

These cases of ankle sprains are treated with the rest and applying ice to the injured area for approximately 20-25 minutes repeated for  3-4 times per day.

Thus, Inversion and 20-25 minutes are the correct answer.
