In hot thermal trenches of deep sea, Archaebacteria can be found, where no other organisms could survive such high temperatures.
Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
I believe that this would be Incomplete Dominance.
The answer should be C, a plain.
Contour lines are used to indicate the height of the land in a map. The closer the contour lines are, the steeper the land will be, as the height of the land changes rapidly.
Therefore, if the contour lines are drawn far apart from each other, most likely the height of the land doesn't changes that much, it remains the same for a larger area, which means a plain should be the answer, as its height doesn't change as much as the other hills, cliff, or valley does.
Answer:
The correct option is E) 1:1:1:1
Explanation:
A punnet square in which only a single trait is being studied is a monohybrid cross. A cross in which two traits are being studied in a dihybrid cross.
As two traits are being studied in the question, hence a dihybrid cross will be made as follows:
A-F A-F OF OF
Bf ABFf ABFf BOFf BOFf
Bf ABFf ABFf BOFf BOFf
Of AOFf AOFf OOFf OOFf
Of AOFf AOFf OOFf OOFf
The results of the punnet square show that there are
- 4/16 chances for the offspring to have the genotype ABFf
- 4/16 chances for the offspring to have the genotype BOFf
- 4/16 chances for the offspring have the genotype AOFf
- 4/16 chances for the offspring to have the genotype OOFf
<em>Hence, there will be an equal ratio of 1:1:1:1 for each of the genotype.</em>
