Final answer:
Anyone of any race can have straight or extremely curly hair. Hair texture is determined by the shape of the hair follicle and the level of curliness is influenced by genetics.
Step-by-step explanation:
Yes, anyone of any race can have straight or extremely curly hair. The texture of hair is determined by the shape of the hair follicle and the level of curliness is influenced by genetics. For example, a person of African descent commonly has tightly curled or kinky hair, while a person of East Asian descent typically has straight hair. However, there is a wide range of hair types within each racial group. The probability of a randomly selected child having wavy hair can be determined by considering the ratio of individuals with wavy hair to the total population. Similarly, the probability of a child having either brown or blond hair can be calculated by summing the ratios of individuals with each hair color. The probability of a child having wavy brown hair can be calculated by multiplying the ratios of individuals with wavy hair and brown hair. Lastly, the probability of a child having red hair given that they have straight hair would depend on the specific population and the frequency of red hair within that population.
