Achild is born with curly hair like her mother's and blue eyes like her father's. why does the child have these features?

"Men have one X chromosome, from their mother, and one Y chromosome, from their father. Because of this, a man will pass his copy of the X chromosome—and the genes it contains—only to his daughters and his copy of the Y chromosome only to his sons. Women have two alleles of every gene on the X chromosome, one inherited from their father and one from their mother. Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father."
