A.Apr 20, 2021 · By crossing the red-haired mice with an albino strain to prevent melanin synthesis, the scientists were able to study the role of pigment. They found that mice carrying the MC1R red-hair variant had a higher pain threshold even without pigment synthesis. However, the number of melanocytes—melanin-producing cells—did affect pain thresholds. Following this pattern of inheritance, you can have a redheaded child given 3 different scenarios: 1. Both you and your partner have red hair = 100% chance of having a redheaded child. 2.
