Think about the genetic trait you selected in previous assignments. Create a genetics word problem involving a simple monohybrid cross with genotypes and phenotypes included that ends in a question with a completed Punnett square and probabilities. Use the rubric to help guide your response. a. Creates a simple monohybrid cross word problem. b. Includes genotype and phenotype of trait c. includes genotype of P1, P2 d. Includes Punnett square showing F1 generation

In a population of rabbits, black fur (B) is dominant over white fur (b). A rabbit breeder decides to cross a black-furred rabbit with a white-furred rabbit to study the inheritance of fur color.

**a.** **Creates a simple monohybrid cross word problem:**

If the black-furred rabbit is homozygous dominant (BB) and the white-furred rabbit is homozygous recessive (bb), what will be the fur color of the offspring in the first filial (F1) generation?

**b.** **Includes genotype and phenotype of trait:**

**Genotype:**

- Black-furred rabbit (P1): BB

- White-furred rabbit (P2): bb

**Phenotype:**

- Black fur (B): Dominant

- White fur (b): Recessive

**c.** **Includes genotype of P1, P2:**

P1: BB (black-furred rabbit)

P2: bb (white-furred rabbit)

**d.** **Includes Punnett square showing F1 generation:**

| | B | b |

|---|---------|---------|

| B | BB | Bb |

| b | Bb | bb |

**Question:**

What are the genotypic and phenotypic ratios of the offspring in the F1 generation?

**Answer:**

- Genotypic ratio: 100% Bb

- Phenotypic ratio: 100% black fur
