Answer:
C) 64% AA, 32% Aa, 4% aa
Explanation:
The frequency of dominant allele A is = 80% = 0.8
Since the population is in Hardy-Weinberg equilibrium, p+ q = 1
Here, p= frequency of dominant allele
q = frequency of recessive allele
Given, p= 0.8
So, q = 1-p = 1-0.8= 0.2
Frequency of genotype AA = p2 = 0.8 x 0.8 = 0.64 = 64%
Frequency of genotype aa = q2 = 0.2 x 0.2 = 0.04 = 4%
Frequency of genotype Aa = 2pq = 2 x 0.8 x 0.2 = 0.32 = 32%
<span>A drumlin differs from a roche moutonnee, in that it is a depositional smooth val shaped small hill up to 1.5 km long and 60 mm tall, having a steep end and a sloping end (elongated in the direction ice flowed). Roche Moutonee is an erosional landform formed when a glacier moving over the top of the rock moves one side giving it a jagged edge and abrading the other side giving it a smooth edge.</span>
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
