Fran's little girl, Fifi, is a real tomboy. Fran asks you to explain why Fifi prefers rough play, boys' clothing and toys, and the company of boys to the company of girls. You believe in the biological explanation of gender development, so you will tell Fran that it is possible that Fifi has:

A. envy.

B. underdeveloped gender identification.

C. gender instability.

D. unusual hormones

My answer is B.

You're probably right.

To determine why Fifi prefers rough play, boys' clothing and toys, and the company of boys, it is important to consider different factors that may contribute to her behavior. While I understand that you believe in the biological explanation of gender development, it's important to note that the preferences and behaviors of individuals can be influenced by a combination of biological, social, and environmental factors.

Regarding the given options, B. underdeveloped gender identification seems to be the most plausible choice based on the information provided. Underdeveloped gender identification refers to a situation where a child may not strongly identify with the typical characteristics and behaviors associated with their assigned gender. Fifi's preferences for rough play, boys' clothing and toys, and the company of boys could indicate that she is exploring her gender identity or does not strongly identify with stereotypical feminine roles and behaviors.

However, it is crucial to remember that child development is a complex process, and there could be other explanations for Fifi's behavior that are not covered by the given options. It is always recommended to consult with professionals such as pediatricians or child psychologists to gain a better understanding of a child's specific situation and to provide appropriate guidance and support.
