Answer:
It's impossible to predict the phenotype of the offspring by only observing the parents because DNA from their grandparents can affect the offspring as well.
Explanation:
DNA is combined from the parents to create offspring. When that offspring reproduces their children not only possess DNA from their parents but from their grandparents as well. Mixing together two separate DNA's from two different family trees can result in rare genetic mutations which results in the offspring looking different from their parents but showing resemblance to their grandparents. This is why you have to look at the phenotypes of more then just the two parents because there are more possibilities, including what their grandparents looked like.

flu is caused by a virus (influenza) NOT bacteria

Answer:
<em>1. They effect crop productivity</em>
As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.
<em>2. They deplete the crops from nutrition</em>
The weeds will compete with the crop plants for resources such as minerals from the soil.
<em>3. They will deplete water resources</em>
The weeds will compete with the crop plants for water.
<em>4. Sun-light will be depleted</em>
The weeds will complete with the crop plants for sun light.
<em>5. The crop quality will be affected</em>
As the crop plants will be in competition with the weeds, hence their quality will be affected.
6. <em>They can reduce the biodiversity of crop plants.</em>
