### Genetic Inheritance in Guinea Pigs In guinea pigs, rough coat (R) is dominant over smooth coat (r), and black coat (B) is dominant over white coat (b). A rough black guinea pig bred with a rough white one produces 29 rough black offspring, 31 rough white offspring, 11 smooth black offspring, and 9 smooth white offspring. **Genotype of the Parents:** - Rough, black parent: RrBb - Rough, white parent: Rrbb **Punnett Square Analysis:** The Punnett square is a grid that predicts the genotypic combinations resulting from a cross between two organisms. Here, it shows the potential combinations of alleles for the offspring from the two guinea pigs: | | RB | Rb | rB | rb | |-------|----|----|----|----| | **RB** | RRBB | RRBb | RrBB | RrBb | | **Rb** | RRBb | RRbb | RrBb | Rrbb | | **rB** | RrBB | RrBb | rrBB | rrBb | | **rb** | RrBb | Rrbb | rrBb | rrbb | **Genotypic Outcomes:** - **RrBb:** 3/8 probability - **Rrbb:** 3/8 probability - **rrBb:** 1/8 probability - **rrbb:** 1/8 probability **Phenotypic Probabilities:** 1. **Rough, black offspring**: 3/8 2. **Rough, white offspring**: 3/8 3. **Smooth, black offspring**: 1/8 4. **Smooth, white offspring**: 1/8 **Expected Numbers from 80 Offspring:** - Rough, black: 30 - Rough, white: 30 - Smooth, black: 10 - Smooth, white: 10 This analysis helps in predicting the likelihood of different traits in offspring based on genotypes of the parents in guinea pigs.
