Question

determine genotype
homozygous dominant(hd), heterozygous (he), or homozygous recessive (hr)
complete the table below.
determine phenotype
complete the table below.
purple flowers are dominant to white flowers
brown eyes are dominant to blue eyes

Explanation:

• For Genotype determination:
• Homozygous Dominant (HD): When an organism has two identical dominant alleles. For example, \(AA\), \(GG\), \(HH\) have two dominant alleles (\(A\), \(G\), \(H\) respectively).
• Heterozygous (He): When an organism has one dominant and one recessive allele. For example, \(Bb\), \(Cc\), \(Dd\), \(Ee\) have one dominant (\(B\), \(C\), \(D\), \(E\)) and one recessive (\(b\), \(c\), \(d\), \(e\)) allele.
• Homozygous Recessive (HR): When an organism has two identical recessive alleles. For example, \(ff\) has two recessive (\(f\)) alleles.
• For Phenotype determination:
• Since purple flowers (\(P\)) are dominant to white flowers (\(p\)), \(PP\) (homozygous dominant) will show the dominant phenotype - purple flowers.
• Since brown eyes (\(B\)) are dominant to blue eyes (\(b\)), \(BB\) (homozygous dominant) will show the dominant phenotype - brown eyes.

Answer:

• Genotype:
• \(AA=\) HD
• \(Ee=\) He
• \(Bb=\) He
• \(ff=\) HR
• \(Cc=\) He
• \(GG=\) HD
• \(Dd=\) He
• \(HH=\) HD
• Phenotype:
• \(PP=\) Purple flowers
• \(BB=\) Brown eyes
