Solution

(N/A) Chromosomes are composed of $DNA$ and proteins. Genes, which are the units of inheritance, are located on these chromosomes. During reproduction, $DNA$ is copied and transferred from both parents to their offspring, ensuring the transmission of hereditary traits. Thus, chromosomes are considered the carriers of heredity.
$(b)$ The sex of the child is not controlled by autosomes; it is determined by the sex chromosomes ($X$ and $Y$).
