Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
<span>Looking at the two species' DNA would be a good place to start. If there are a number of similarities in their genotypes, then there would be a good chance that the two would also share some type of a common ancestor. This would be evidence that there was some type of selection that took place that necessitated two different species that shared a number of traits and features.</span>
Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.
