If p = frequency of A and q = frequency of a, then assuming H-W equilibrium we have
p + q = 1 ⇒ q = 1 - p = 1 - 0.55 = 0.45
Then the expected frequency of the heterozygous genotype Aa is 2pq = 2 • 0.55 • 0.45 = 0.495.
Answer:
They both have cell membranes.
Explanation:
The prokaryotes and eukaryotes have cell membranes that enclose the cell organelles. The prokaryotes lack nuclear membrane, membrane bound organelles like the chloroplasts and also golgi apparatus.
The answer is; It provided clues for scientists to develop a hypothesis about the origin of flight.
Scientists now postulate that dinosaurs are the ancestors of birds. This because the Microraptor is a dinosaur with feathers in all its limbs. It is also the smallest dinosaur to every been discovered and has been compared with the Archaeopteryx (involving even genetic sequencing) to hypothesize how dinosaurs evolved into birds.
