Answer:
4
Explanation:
If both parents were Hetero brown, they would both have this allele: Bb.
If you were to draw a punnet square, the outcomes would be: BB, Bb, Bb, and bb.
There would be a 75% chance of the offspring having brown eyes and a 25% chance of the offspring having blue eyes.
Also the alimentary canal or digestive tract
There are two events,
A: the selection belongs to the specific species, or
A' : the selection does not belong to the specific species.
The answer is true

Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
