Answer:
- Half (8/16) of the offspring will have gray fur and black eyes.
- Half (8/16) of the offspring will have gray fur and red eyes.
- None (0/16) of the offspring will have white fur.
Explanation:
For the purposes of this question, we will assume the following notation for the involved alleles:
G: gray fur (dominant), g: white fur (recessive).
B: black eyes (dominant), b: red eyes (recessive).
A GGbb rabbit may only produce one type of gametes, namely Gb.
A ggBb rabbit may produce either gB or gb gametes.
Since not all theoretical combinations are present, the resulting Punnett square may be simplified as follows:
| Gb
——-+-————
gB | GgBb
——-+-————
gb | Ggbb
As seen above, 100% of the offspring will have a Gg genotype (resulting in gray fur). As for eye color, half of them will have a Bb genotype (resulting in black eyes) whereas the other half will have a bb genotype (red eyes).
