Which pattern of inheritance results from individual organisms having many different genes working at the same time to control a

saw5 [17]

The answer is polygenic inheritance.
Many physical characters (traits) depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.

For example, the color of the skin in humans. The color of the skin results from the interactions of several factors determined by different pairs of genes:-Certain genes could affect the metabolism of skin melanocytes.-Other genes can determine the distribution of melanin in the thickness of the skin.-Some genes could determine the relative amounts of each of the two possible types of melanin.-Others may affect the production of certain hormones involved in the activity of melanocytes.

Nutka1998 [239]

Given that organisms accumulate contaminants into their bioavailable fractions, we can conclude that the most likely outcome of this pollutant on the oysters is that heavy metals will bioaccumulate in the oysters.

Heavy metals that are often found in water include:

Lead
Copper
Arsenic
Cadmium
Manganese

and more.

Though some metals are water-soluble, this does little to lessen the negative impact of their presence in the water. Water is used as an essential resource for all life. Metals in high concentrations, even those soluble in water, have been shown to be fatal to many organisms, including oysters.

Though oysters would suffer to a degree from biomagnification, which is the accumulation of toxins in an organism through the food chain, this will most likely become a serious problem higher up on the food chain, as the oysters are consumed by predators.

The most likely outcome of these pollutants in the water is that the Heavy metals will bioaccumulate in the oysters. This is due to the fact that the oysters will absorb the metals from the water. At high enough concentrations, this will lead to a decrease in the number of oyster offspring, possibly even reducing it to half.
