Answer:
Increased levels of phosphate are beneficial to phytoplankton and aquatic plants. In the short-run, this means increased micronutrients for herbivorous and omnivorous fish.
The phosphate, however, reacts with the water to reduce the oxygen levels obtainable in the water. Without oxygen, the fishes die off.
It is not unusual to find that with increased phosphate in water, healthy fishes begin to die off without any other plausible explanation.
The solution is to clean the water or treat it with solutions that impact positively whilst reducing the phosphate levels.

<h2>Law of independent assortment </h2>
Explanation:
- There are 8 distinct phenotypes, each one has a 12,5% of appearance: Since M=solid leaves D=normal height P= smooth skin.
- Recessive gene characters can only be taken in homozygous recessive mmddpp.
1. MmDdPp: M=solid leaves D=normal height P= smooth skin.
2. MmDdpp M=solid leaves D=normal height pp= peach skin.
3. MmddPp M=solid leaves dd=dwarf height P= smooth skin.
4. Mmddpp M=solid leaves dd=dwarf height pp= peach skin.
5. mmDdPp mm=mottled leaves D=normal height P= smooth skin.
6. mmDdpp mm=mottled leaves D=normal height pp= peach skin.
7. mmddPp mm=mottled leaves dd=dwarf height P= smooth skin.
8. mmddpp mm=mottled leaves dd=dwarf height pp= peach skin.
Hence,The answer is all eight possible phenotypes from the cross MmDdPp x mmddpp are equally likely, resulting in a phenotypic ratio of 1:1:1:1:1:1:1:1
