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.
People with achondroplasia have short stature, with an average adult height of 131 centimeters (52 inches) for males and 123 centimeters (48 inches) for females. Achondroplastic adults are known to be as short as 62.8 cm (24.7 in).If both parents of a child have achondroplasia, and both parents pass on the mutant gene, then it is very unlikely that the homozygous child will live past a few months of its life. The prevalence is approximately 1 in 25,000.chondroplastic adults are known to be as short as 62.8 cm (24.7 in). If both parents of a child have achondroplasia, and both parents pass on the mutant gene, then it is very unlikely that the homozygous child will live past a few months of its life.
