Phenotypic Ratio of Dogs Crossing Heterozygous for Barking and Erect Ears with Homozygous Recessive Dogs
Explanation:
When two traits are considered, barking and ear position, and a cross is made between a heterozygous dog for both traits and a homozygous recessive dog for both traits, the phenotypic ratio will be 1:1.
Genotypes of Parental Dogs:
- Heterozygous dog for barking trait: Bb
- Heterozygous dog for erect ear trait: Ee
- Homozygous recessive dog for barking trait: bb
- Homozygous recessive dog for drooping ear trait: ee
Possible Genotypes of Offspring:
- BbEe: Barking with erect ears
- bbEe: Silent with erect ears
- Bbee: Silent with drooping ears
- Bbee: Barking with drooping ears
Phenotypic Ratio:
- 50% of the offspring will have the dominant traits (barking and erect ears)
- 50% of the offspring will have the recessive traits (silent and drooping ears)
Conclusion:
The phenotypic ratio of dogs crossing heterozygous for barking and erect ears with homozygous recessive dogs is 1:1. This means that half of the offspring will have the dominant traits of barking and erect ears while the other half will have the recessive traits of silence and drooping ears.
