Yes, It is possible that a recessive trait…

    This study is a quantitative-descriptive in nature where the purpose is to describe the level of student’s satisfaction on services provided by the school towards the enrollment system through quantitative research method to quantify and reflect in numbers the observation made of the respondents being studied (Sampa, 2012).
