Improved Physical Fitness: Improves children's muscular strength, flexibility, muscular endurance, body composition and cardiovascular endurance.
Skill Development: Develops motor skills, which allow for safe, successful and satisfying participation in physical activities.
Regular, Healthful Physical Activity: Provides a wide-range of developmentally appropriate activities for all children.
Support of Other Subject Areas: Reinforces knowledge learned across the curriculum. Serves as a lab for application of content in science, math and social studies.
Self Discipline: Facilitates development of student responsibility for health and fitness.
Improved Judgment: Quality physical education can influence moral development. Students have the opportunity to assume leadership, cooperate with others; question actions and regulations and accept responsibility for their own behavior.
Stress Reduction: Physical activity becomes an outlet for releasing tension and anxiety, and facilitates emotional stability and resilience.
Strengthened Peer Relationships: Physical education can be a major force in helping children socialize with others successfully and provides opportunities to learn positive people skills. Especially during late childhood and adolescence, being able to participate in dances, games and sports is an important part of peer culture.
Improved Self-confidence and Self-esteem: Physical education instills a stronger sense of self-worth in children based on their mastery of skills and concepts in physical activity. They can become more confident, assertive, independent and self-controlled.

Answer:
b. 3
Explanation:
Dominant genes are represented by capital letters (such as the "O" used to show that the obesity gene is dominant) and phenotypically expressed as heterozygosis (Ot) or homozygosis (OO). These genes are those that determine a hereditary trait even when in single dose genotypes. That is, they determine their character even in the absence of their dominant allele.
Recessive genes are represented by lowercase letters (such as the "t" used to show that the thinness gene is recessive) where phenotypes are expressed only in homozygosis (tt). Thus, only the individual who presents tt genes, among the options given in the question, will not present obesity.
Gilligan represents the only person who does not have the "O" allele, his alleles are "tt", so Gilligan will not be obese. However, Ginger, who is "OO", Mary Ann, who is "Ot" and Thurston, who is "tO", have the dominant allele responsible for obesity, so from the options given, we can say that 3 individuals have the highest probability to be obese.
