401 of these offspring are expected to have long plumage.
To calculate the number of these offspring that are expected to have long plumage the following cross multiplication calculation must be performed:
- Total birds = 72 + 252 = 324
- Long plumage birds = 55 + 75 = 130
- 324 = 130
- 1000 = X
- 1000 x 130/324 = X
- 130000/324 = X
- 401.23 = X
Therefore, 401 of these offspring are expected to have long plumage.

Answer: <u>Option D point source pollution
</u>
Explanation: The pollutants which can be tracked, from the source of origin are termed as point source pollution. This can be water source, air or even light or noise pollution.
