ARα and ARβ play distinct roles in the control of testes mass and coloration. (A) ARα+/+ males have smaller testes than ARαd50/d50 males, while ARαd50/+ males were not different from either group. (B) ARβ+/+ males have larger testes than ARβd5/+ males, which have larger testes than ARβd5/d5 males. (C) ARα mutant males do not look different from ARα+/+ males (D) while ARβ mutant males lack the dominant-typical yellow coloration seen in ARβ+/+ males. (E) ARβ+/+ males possessed more “very dark yellow” (#55551C) pixels than ARβd5/+ males, which had more dark yellow pixels than ARβd5/d5 males, (F) while ARβd5/d5 males had more “dark grayish yellow” (#80806A) pixels than both ARβd5/+ and ARβd5/d5 males. +, wild type; d, deletion.
