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
Answer - B
Reason - Since the area is in the tropics there will be time to time heavy precipitation, which over time the decomposed nutrients will get washed down into a run off and depleted.
These had no leaves or roots, instead they had green photosynthetic stems which served as both anchors in the ground and photosynthetic surface.
