Unfortunately you do not tell us which trait is dominant so we need to assume that dark mice light mice and medium colored are all possible.
The answer is K-selected.
Based on the evolutionary strategies, species can be r-selected or K-selected. The characteristics of K-selected species are: large size of organisms, long lifespan, late maturity, few offspring, etc. On the contrary, the characteristics of r-selected species are: small size of organisms, short lifespan, early maturity, many offspring, etc
he entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
They absorb food from their environment and release ammonia into their environment through their body surface because their body is very flat, due to the lack of coelom
Hope this helped
