Explanation:
In general, photosynthesis in cyanobacteria uses water as an electron donor and produces oxygen as a byproduct, though some may also use hydrogen sulfide a process which occurs among other photosynthetic bacteria such as the purple sulfur bacteria. Carbon dioxide is reduced to form carbohydrates via the Calvin cycle.
Answer:
The correct answer would be - 0.1 a, 0.9 A
Explanation:
The initial population of the colonist had free earlobes which are represented by A here as it is dominant and attached is represent by a. purebred dominant would have AA.
Frequency of allele A =
8 pure dominant and 2 heterozygous dominant presents in the population
So, frequency of A allele = 8 x 2 + 2 / 20
= 18/20
= 0.9
As we know
p+q=1;
frequency of allele "a" = 1-p
= 1-0.9
= 0.1
