Four TAFs do have some intrinsic DNA binding ability: TAF4b, TAF12, TAF9, and TAF6 are (distant) homologs of histones H2A, H2B, H3, and H4, respectively.  TAF4b/TAF12 and TAF9/TAF6 form heterodimers using the histone fold motif

An individual without gonads will leave no genes to the next generation. Gonads and genitalia are called primary sexual traits.

Secondary sexual traits, which differ between the sexes but do not play a direct role in reproduction.
