Biomagnification is when toxins / heavy metal are present in small amounts in fish, but accumulate as you move into higher trophic levels. This is one reason why it can be toxic for humans to eat tertiary or quaternary consumers, such as swordfish, shark, etc.

Answer:
WwNn
Explanation:
- Long wings (W) are dominant over short wings (w)
- Brown pigments (N) are dominant over yellow pigments (n)
A fly that is homozygous dominant for both traits (WWNN) is crossed with a fly that is homozygous recessive for both traits (wwnn).
All gametes produced by the WWNN individual will be <em>WN,</em> and all gametes produced by the homozygous recessive individual will be <em>wn</em>.
When the gametes from the two parents combine, the zygote will be heterozygous for both genes, with the genotype WwNn.
