In rabbits spotted coat S is dominant to solid color s while

In rabbits, spotted coat S is dominant to solid color s, while for coat color, black 8 is dominant to brown b. A brown spotted rabbit is mated with a solid black one and all the offspring are black spotted (the genes are not linked). (a) State the genotypes: Parent 1: _______ Parent 2: _______ Offspring: _______ (b) Use the Punned square to show the outcome of a cross between the F_1 (the F_2): (c) Using ratios, state the phenotypes of the F_2 generation:

Answer:

Spotted coat = S

Solid color= s

Black coat= B

Brown coat = b

(a)

Parent 1

Brown spotted (SSbb)

Parent 2

Solid black (ssBB)

Offspring: Black spotted (SsBb)
