Andrew Is Genetically Male,and He Believes That His Y Chromosome

Andrew is genetically male,and he believes that his Y chromosome is the source of a large number of sex differences between his genetically female sister and himself.Is he correct?

A) No,because there are not actually any sex differences between genetically male and genetically female individuals.
B) No,because the Y chromosome only has a minimal impact on genetically male individuals.Research suggests it simply gives XY fetuses functioning testes and facilitates male fertility.
C) Yes,because the Y chromosome has a large impact on genetically male individuals.It not only gives XY fetuses functioning testes and facilitates male fertility,but it also explains why males are more susceptible to recessive traits than females.
D) Yes,because the Y chromosome is far larger than the X chromosome and has 10 times as much genetic material.
