Color: Different species of the Newts are of different color. They come in green, blue, black, brown, yellow, red and even orange shades. Anatomy: They have teeth on both the jaws and possess external gills. Their limbs, spinal cord, heart, eyes, intestines, tail and both the jaws can regenerate.
Head control is also delayed, and the majority of children with the condition are unable to hold their heads up independently until after seven months of age. Children with achondroplasia start to walk at approximately 18 months and at two and a half years old around 90 per cent of them can walk.The delay is the result of a combination of muscular weakness in the legs, hypermobility of the knee joints and an unusually large, heavy head, which is difficult to balance.f two people with achondroplasia have a child, there is a 25 per cent risk that the child will receive two copies of the mutated gene (a homozygote for this particular gene) causing significant skeletal abnormalities.
All people with achondroplasia have short stature. The average height of an adult male with achondroplasia is 131 centimeters (4 feet, 4 inches), and the average height for adult females is 124 centimeters (4 feet, 1 inch).wo specific mutations in the FGFR3 gene are responsible for almost all cases of achondroplasia. Researchers believe that these mutations cause the FGFR3 protein to be overly active, which interferes with skeletal development and leads to the disturbances in bone growth seen with this disorder.
