Question
for each genotype below, indicate whether it is heterozygous or homozygous. genotypes shown in image: yy, bb, dd, zz, oo, dd, mm, ii, dd, bb, ww, aa (arranged in vertical bars with connecting dots below)
Response
To determine if a genotype is heterozygous or homozygous, we use the following rules:
- Homozygous: Both alleles (the two forms of a gene) are identical (e.g., \( AA \), \( aa \), \( BB \), \( bb \), \( ZZ \), \( OO \), \( mm \), \( II \), \( DD \), \( FF \), \( WW \)).
- Heterozygous: The two alleles are different (e.g., \( Aa \), \( Bb \), \( Zz \), \( Oo \), \( Mm \), \( Ii \), \( Dd \), \( Ff \), \( Ww \)).
Genotype \( WY \)
- Alleles: \( W \) and \( Y \) (different).
- Classification: Heterozygous.
Genotype \( BB \)
- Alleles: \( B \) and \( B \) (identical).
- Classification: Homozygous.
Genotype \( Dd \)
- Alleles: \( D \) and \( d \) (different).
- Classification: Heterozygous.
Genotype \( ZZ \)
- Alleles: \( Z \) and \( Z \) (identical).
- Classification: Homozygous.
Genotype \( Oo \)
- Alleles: \( O \) and \( o \) (different).
- Classification: Heterozygous.
Genotype \( aa \)
- Alleles: \( a \) and \( a \) (identical).
- Classification: Homozygous.
Genotype \( mm \)
- Alleles: \( m \) and \( m \) (identical).
- Classification: Homozygous.
Genotype \( II \)
- Alleles: \( I \) and \( I \) (identical).
- Classification: Homozygous.
Genotype \( DD \)
- Alleles: \( D \) and \( D \) (identical).
- Classification: Homozygous.
Genotype \( FF \)
- Alleles: \( F \) and \( F \) (identical).
- Classification: Homozygous.
Genotype \( WW \)
- Alleles: \( W \) and \( W \) (identical).
- Classification: Homozygous.
Genotype \( Aa \)
- Alleles: \( A \) and \( a \) (different).
- Classification: Heterozygous.
Final Classifications:
| Genotype | Classification |
|---|---|
| \( BB \) | Homozygous |
| \( Dd \) | Heterozygous |
| \( ZZ \) | Homozygous |
| \( Oo \) | Heterozygous |
| \( aa \) | Homozygous |
| \( mm \) | Homozygous |
| \( II \) | Homozygous |
| \( DD \) | Homozygous |
| \( FF \) | Homozygous |
| \( WW \) | Homozygous |
| \( Aa \) | Heterozygous |
