Answer:
To determine the expected phenotypic ratios and genotypic ratios of the offspring, we can use a Punnett square. Let's assign the following letters for the alleles:
A - Gray fur (dominant)
a - White fur
B - Black eyes (dominant)
b - Red eyes
Based on the information given:
Parent 1: Gray fur (Aa) and red eyes (bb)
Parent 2: White fur (aa) and black eyes (Bb)
Punnett square:
| Aa Aa aA aA |
_______|______________________|_______
Bb | ABb ABb aBb aBb |
_______|______________________|_______
Bb | ABb ABb aBb aBb |
_______|______________________|_______
To determine the phenotypic ratios, we can analyze the genotypes in the Punnett square:
- Phenotypically, gray fur (A) is dominant over white fur (a), and black eyes (B) are dominant over red eyes (b).
Phenotypic ratios:
- Gray fur and black eyes (A-B-): 4/4 or 100%
Genotypic ratios:
- A-B- (gray fur, black eyes): 4/4 or 100%
In summary, all the offspring from this cross are expected to have gray fur and black eyes.
