Q. Imagine a scenario where a female human is born to a mother with light skin and a father with dark skin. Assume that skin color is determined by one gene. The child's skin is one consistent color. What is the best reason for why a female human does not have splotches of dark skin and splotches of light skin?
The gene for skin color is located on the X chromosome.
The gene for skin color is not located on the X chromosome.
Transcriptional silencing is occurring.
The pigment gene is transcribed regularly.
The pigment gene from the dad was lost in development.
