Answer:
B.chickens are more closely related to ducks than they are to humans.
Explanation:
Amino acids are coded for by codons.
Codons are sequence of nucleotide bases from mRNA.
mRNA are synthesized using DNA templates.
Therefore, the more similar the amino acid sequence of two organisms, the more genetically related the organisms are.
<em>Chickens and ducks had amino acid sequence of 3 while chickens and humans had 13. It thus means that chickens and ducks are more related as compared to chickens and humans.</em>
The correct option is B.
Mitochondrial and thylakoid membranes both use adenosine triphosphate or ATP synthase proteins in atp production.
Since the two species co-inhabit the same habitat, habitat isolation can be disregarded as a factor keeping the two species separate. There are however some other broad categories of mechanisms for <span>reproductive isolation. One is behaviour. Many birds in particular have very specific mating rituals, including mating dances, particular bird song, the development of specific mating plumage, the release of specific pheromones and the building of a particular nest structure. Another broad category is mechanical isolation. You will find that the genital organs of particular species are very specific, and preclude other close species from successfully mating. Another broad category is gametic isolation. For most species combinations, it is not possible for the gametes to fuse successfully to form a hybrid. If hybrid games do fuse, in many cases, the hybrids are sterile, such as mules for example. </span>
