based on the information provided in figure 1 and figure 2, which of the following best predicts the effects of a mutation in the promoter of the tyr gene that prevents it from being transcribed?

Respuesta :

Based on the information provided in figure 1 and figure 2, Skin pigmentation will not be altered, leading to a negative selection pressure.

What is the figure about?

The Figure shows the making of α-MSH in keratinocytes as a result of UV radiation.

The option that  effects of a mutation in the promoter of the tyr gene that prevents it from being transcribed is that Skin pigmentation will not be altered, leading to a negative selection pressure.

Conclusively, in  Figure 1, TYRTYR is needed for the steps in the melanin synthesis pathway but when it was not shown properly, it hinders melanocytes from synthesizing melanin even if there was an exposure to UVUV radiation. This would therefore leads to a negative selection pressure.
