damaskus [11]

Answer:

The correct answer is - 0.084

Explanation:

Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.

Normal allele is represented by - HbA - p

sickel cell allele is represented by - HbS - q

genotype frequency of normal allele HbA in the population = p2

genptype frequency of HbAHbS in the population = 2pq

genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)

So, the allelic frequency of the recessive allele =

q =  √ 0.007 = 0.08366 or 0.084

Describe the two different notations used to specify isotopes and give an example of each.
Georgia [21]
There are two ways that can be used to name isotopes of an element. This is best illustrated by examples. We'll use the element chlorine for simplicity.

The first example is the more common one. The formula for this notation is E-m where E is the name of the element and m is the mass number. 
(1) Chlorine-35
(2) Chlorine-37
(3) Chlorine 38

Another is less commonly used. The formula for this notation is m^ a L where m is the mass number, a is the atomic number and L is the first letter of the element.
(1) 35^ 35 Cl
(2) 37^ 35 Cl
(3) 38^ 35 Cl
