In guinea pigs, the allele for short hair is dominant to long hair. A guinea pig with short hair is crossed to one that has long hair. Over a period of years, a scientist keeps records of the offspring and finds that 44 of them have short hair and 46 of them have long hair. Based on this data, what are the genotypes of the parents: 1. HH x hh
2. Hh x hh
3. HH x Hh
4. hh x hh
