Which variety is represented by shades such as agouti and shaded patterns?

The correct choice refers to the Holland Lop breed, which encompasses a variety of color patterns including agouti and shaded varieties. Agouti patterns present a ticking effect where individual hairs have multiple colors along their length, creating a speckled appearance. Shaded patterns involve a distinct color gradient on the rabbit's coat, often with a lighter undercoat and a darker top layer. This breed is known for its diverse array of colors and patterns, making it popular among show rabbit enthusiasts.

The other breeds listed do not typically include agouti and shaded qualities in their recognized color patterns. For example, the Dwarf Papillon is characterized by its unique color markings and patterns, but does not emphasize agouti or shading. The Himalayan breed is recognized primarily for its solid color body and contrasting darker points, rather than the complexity of shading found in agouti varieties. Finally, the English Spot features a specific pattern of spots along with a different coat coloring that does not align with agouti or shaded patterns. Thus, Holland Lop stands out as the breed associated with these specific varieties.
