Answer
Here's how to solve this guinea pig genetics problem:1. **Identify the Trait and Alleles:** The trait is hair length. Long hair (L) is dominant over short hair (l).2. **Determine the Genotypes:** * George is heterozygous for long hair, meaning he has one dominant allele (L) and one recessive allele (l). His genotype is Ll. * Greta has short hair. Since short hair is recessive, she must have two recessive alleles (ll). Her genotype is ll.3. **Set up a Punnett Square:** A Punnett square helps visualize the possible combinations of alleles from the parents. ``` L | l ------- l| Ll | ll ------- l| Ll | ll ```4. **Analyze the Results:** The Punnett square shows the following possible genotypes for their offspring: * Ll (Long hair): 2 out of 4 possibilities (50%) * ll (Short hair): 2 out of 4 possibilities (50%)**Answer:** The chances of George and Greta having a baby guinea pig with short hair are 50%. So the correct answer is option 3.
