Answer:
0%
Explanation:
Achondroplasia is an autosomal dominant disorder that is expressed in both homozygous and heterozygous dominant genotypes. Since two affected parents have a normal girl child, both the parents should be heterozygous carrier for the disease. Let's assume that the dominant allele "A" is responsible for the disease. Genotype of both the parents of the girl would be "Aa". The genotype of girl with normal stature is "aa". Genotype of her normal partner is "aa".
A cross betwee aa X aa would get all the progeny with "aa" genotype. Therefore, all of their children would have normal stature and there is 0% probability for them to have a child with achondroplasia.

Retraction occurs in the scapula (Shoulder blades) and mandible (jaw). Dorsiflexion you see that happen in your foot. When you bring your toes closer to the shin. Supination is more on the forearm and foot, where you rotate it so your palms are facing forward (sole facing the other ankle for feet). Flexion is the movement of body parts where you bring them closer to each other at a joint (the angle between the two parts are lessened). Like when you bend your elbows to "flex" muscles.
