Question

choose the phenotype to go with each genotype. be sure to pay attention to the homozygous dominant and homozygous recessive pairs. (need a refresher? watch this video on heterozygous and homozygous)
genotypes: bb, bb, bb, gg, hh, rr, ee
phenotype categories: homozygous dominant, heterozygous, homozygous recessive

Explanation:

Step1: Recall Genotype Definitions

• Homozygous Dominant: Two identical dominant alleles (e.g., \( AA \)).
• Heterozygous: Two different alleles (e.g., \( Aa \)).
• Homozygous Recessive: Two identical recessive alleles (e.g., \( aa \)).

Step2: Classify Each Genotype

• \( BB \): Homozygous Dominant (two dominant \( B \) alleles).
• \( Bb \): Heterozygous (one \( B \), one \( b \)).
• \( bb \): Homozygous Recessive (two recessive \( b \) alleles).
• \( Gg \): Heterozygous (one \( G \), one \( g \)).
• \( Hh \): Heterozygous (one \( H \), one \( h \)).
• \( rr \): Homozygous Recessive (two recessive \( r \) alleles).
• \( EE \): Homozygous Dominant (two dominant \( E \) alleles).

Answer:

• Homozygous Dominant: \( BB \), \( EE \)
• Heterozygous: \( Bb \), \( Gg \), \( Hh \)
• Homozygous Recessive: \( bb \), \( rr \)
