Answer:
Achondroplasia
Explanation:
Achondroplasia is a genetic disorder that comes from the inability to change cartilage into bone, especially in long bone. The characteristic of the disease is short stature, large head, vertebral abnormalities, and many other possible symptoms. It's inherited genetically by a dominant pattern, but most cases come from a mutation from a parent that has no defect gene. It is the most common cause of dwarfism.
Active transport: Movement of materials across a membrane that requires an input of energy from a cell. Movement of material against the concentration gradient (from low concentration to high concentration)
Passive transport: Movement of materials across a membrane that does not require energy from the cell. Movement of material against the concentration gradient (from high concentration to low concentration)

Worldwide, there are 107 boy babies born for every 100 girl babies. This skewed ratio is partly due to sex-selective abortion and "gendercide," the killing of female infants, in countries such as China and India where males are more desired. But even discounting those factors, the completely natural male-to-female sex ratio still hovers around 105:100, meaning that women are inherently more likely to give birth to boys. Why?
Several factors influence whether a sperm containing a Y sex chromosome or one containing an X chromosome will be first to fertilize an egg, including parental ages, their environmental exposure, stress, the stage in the mother's ovulation cycle and even whether she has had children previously; all these forces combine to set the average sex ratio at fertilization at 105:100.
