Use the following information to answer questions 10 and 11.

The following is known about the inheritance of size and fur color in Holland lop rabbits:

• Crosses between large individuals only produce large individuals.
• Crosses between dwarf individuals produce both large and dwarf rabbits in a ratio of 1:2. Such crosses also produce some very small kits (baby rabbits) that generally die within a few days.
• Crosses between brown rabbits only produce brown kits.
• Some crosses between black rabbits produce only black kits, whereas others produce both black and brown kits.
• The size and fur color phenotypes segregate independently.

10.  What are the expected phenotypes in the F₁ of a cross between a dwarf rabbit that breeds true for brown fur color and a large rabbit that breeds true for black fur color?

A) black dwarf only

B) black dwarf and black large only

C) brown dwarf and black dwarf only

D) brown dwarf, brown large, black dwarf, and black large

E) brown large only 

Answer: B
