About the question:
I failed to find the complete question with the Punnett square, so in the answer and explanation I will propose five options for crosses between dogs with different genotypes, and for each option, I will remark the percent of the offspring that is expected to have wirehair. You just need to look for the option that matches your Punnett Square.
Answer:
- Option 1: HH x HH ----> 100% of the progeny is wire-haired, HH
- Option 2: HH x Hh---> 100% of the progeny is wire-haired, HH + Hh
- Option 3: Hh x Hh --->75% of the progeny is wire-haired, 25% HH + 75% Hh
- Option 4: Hh x hh ---> 50% of the progeny is wire-haired, Hh
- Option 5: hh x hh ----> 0% of the progeny is wire-haired
Explanation:
You will find the complete explanation in the attached files due to technical problems
