Answer:
If both parents have wavy hair and round faces, it would suggest that these traits are likely dominant. However, it's important to note that even if both parents exhibit these traits, they could still carry recessive genes for straight hair and angular faces. When they reproduce, the child has a 25% chance of inheriting two recessive alleles for each trait (e.g., ww and rr), resulting in neither wavy hair nor a round face.
