Hair is made of keratin, a protein fiber somewhat like wool. Whether hair is straight or curly is determined by your genes. The fiber of straight hair is round, while the fiber of wavy of curly hair is oval. In addition to genes, hormones also influence hair texture, and hair texture can change throughout a person's life, especially during times like puberty.
All of their children will have straight hair, as the father can only pass on the dominant straight hair allele. The children will inherit one straight hair allele from their father and one curly hair allele from their mother, but the dominant straight hair allele will mask the recessive curly hair allele.
If you have straight hair of curly hair. I think straight haris is dominant.
