Greg's mom has bushy eyebrows. Greg's dad has a large nose. Greg has bushy eyebrows and a large nose. Which statement correctly explains what structures of the cell are responsible for the inheritance of Greg's traits?
A) Facial traits like nose size and eyebrow size are sex linked traits so they are located on the X and Y chromosome. Heredity is the passing of sex linked traits only.

B) Each gene is located inside the ribosome of each cell and when it undergoes DNA synthesis, traits are passed from one cell to another. Heredity is the passing of traits during DNA synthesis.

C) Each gene is located on a section of DNA of the chromosome. Inside each cell, this DNA contains instructions for each person. Heredity is the passing of these genes from Greg's parents to him.

D) Each trait that Greg inherits from his parents are inherited from his parents, including his big nose and his bushy eyebrows. These traits are produced during cellular respiration. Heredity is the passing of traits during cellular respiration.

C is the correct answer. A is not correct because we do not know if nose size and eyebrow size are sex linked traits - nothing in the question suggests this. Moreover, heredity is not just the passing of sex linked traits. Heredity also includes traits that are not sex linked. B is not correct because genes are not located inside ribosomes. Genes are located on DNA. DNA synthesis does not cause heredity. DNA synthesis is the replication of the DNA prior to cell division. D is not correct. C is the correct answer because genes are located on DNA that is contained in a chromosome. DNA contains information about proteins. The information is hereditary, or passed down, from parent to child.
