Hypothesize how some people have red hair through viable errors. Explain your answer in 1-2 sentences.

DENIUS [597]

Considering a viable error as a mutation that remains viable for the continuation of life, we can confirm that some people have red hair through viable errors due to mutations in the genetic code.

A viable error or mutation would be any mutation that allows the cell in question to stay alive. This is because there are mutations in which key features or processes essential to life are altered.

The cells that suffer these mutations would not be able to sustain life. The mutation that causes red hair is a mutation in the gene responsible for melanin (the pigment that gives hair its color) is not one that affects an essential process.

For this reason, we can confirm that some people have red hair through viable errors given that these errors or mutations do not affect mechanisms essential to life.
