Mike and his three brothers all have brown hair. Mike's father has brown hair, too. Mike's mother, however, is the only family member that has red hair color. What conclusion can you draw about the gene for hair color?
the gene for red hair is dominant over the gene for brown hair
the gene for brown hair is dominant over the gene for red hair
gene's for red and brown hair are co-dominant
