A certain species of rabbit can have either black or grey fur. The allele for black fur is dominant over the allele for grey fur. If a homozygous black rabbit is crossed with a heterozygous black rabbit, what phenotypic ratio will occur in the first generation? OA 100% black: 0% grey OB. 50% black: 50% grey OC. 75 % black: 25% grey OD. 25% black: 75% grey

### Inheritance Patterns and Genetic Research: Mastery Test

#### Question 1:

A certain species of rabbit can have either black or grey fur. The allele for black fur is dominant over the allele for grey fur. If a homozygous black rabbit is crossed with a heterozygous black rabbit, what phenotypic ratio will occur in the first generation?

**Options:**
A. 100% black : 0% grey  
B. 50% black : 50% grey  
C. 75% black : 25% grey  
D. 25% black : 75% grey  

**Functional Buttons:** 
1. **Reset** - This button allows the user to reset the chosen option.
2. **Next** - This button allows the user to proceed to the next question.

**Note:** Ensure you understand the concept of dominant and recessive alleles as well as how to calculate phenotypic ratios using Punnett squares for accurate determination of the correct answer.
