Question

Vocabulary practice! Fill in missing boxes assuming that having hair for guinea pigs follows Mendelian
inheritance, where the H dominant allele codes for hair and h codes for a lack of hair (hairless).
Image Genotype Heterozygous or
Homozygous?
Phenotype
HH 1. 2.
3. 4. Hairless
5. 6. Heterozygous 7.

Answer 1

Certainly! Let's fill in the missing boxes regarding the genotypes, their classifications as homozygous or heterozygous, and phenotypes based on Mendelian inheritance for hair in guinea pigs.

1. **Image Genotype**: **HH**
- **Heterozygous or Homozygous?**: **Homozygous**
- **Phenotype**: **Hair**

2. **Image Genotype**: **Hh**
- **Heterozygous or Homozygous?**: **Heterozygous**
- **Phenotype**: **Hair**

3. **Image Genotype**: **hh**
- **Heterozygous or Homozygous?**: **Homozygous**
- **Phenotype**: **Hairless**

4. **Image Genotype**: **Hh**
- **Heterozygous or Homozygous?**: **Heterozygous**
- **Phenotype**: **Hair**

5. **Image Genotype**: **HH** (repeated for clarity)
- **Heterozygous or Homozygous?**: **Homozygous**
- **Phenotype**: **Hair**

6. **Image Genotype**: **Hh** (repeated for clarity)
- **Heterozygous or Homozygous?**: **Heterozygous**
- **Phenotype**: **Hair**

7. **Image Genotype**: **hh** (repeated for clarity)
- **Heterozygous or Homozygous?**: **Homozygous**
- **Phenotype**: **Hairless**

Here’s a summary of the completed table:

| Image Genotype | Heterozygous or Homozygous? | Phenotype |
|----------------|------------------------------|-----------|
| HH | Homozygous | Hair |
| Hh | Heterozygous | Hair |
| hh | Homozygous | Hairless |
| Hh | Heterozygous | Hair |
