Explanation:
All males who inherit the mutation will be affected, and all females who inherit the mutation will be carriers. Because it is not possible for a male to be an unaffected carrier of X-linked SCID, parents cannot both be carriers of this type.
In research when a significant result is found that means it has been shown through statistical tests that one variable has had an effect on another. If it is a low effect size though it means that the effect is not large enough to prove a hypothesis.

Answer: The answer is C- Movement of the abdomen with respiratory effort.
Explanation:
Adults require the coordinated use of the diaphragm, the intercostal muscles and the abdominal muscles for breathing.
However babies and young children make use of the abdominal muscles to pull the diaphragm down for breathing. Their intercostal muscles are not yet fully developed at birth. It is therefore easy to observe respiratory distress by observing the movement of the abdominal muscles.
