Question

in a group of bitter melon plants, some individuals have dark brown seeds and others have light brown seeds. in this group, the gene for the seed color trait has two alleles. the allele d is for dark brown seeds, and the allele d is for light brown seeds. a certain bitter melon plant from this group has dark brown seeds. this plant has two alleles for dark brown seeds. based on this information, what is this bitter melon plant’s phenotype for the seed color trait? dark brown seeds dd

Explanation:

Step1: Recall Phenotype Definition

Phenotype is the observable trait. Here, seed color is the trait.

Step2: Analyze Alleles and Trait

Allele \( D \) is for dark brown, \( d \) for light brown. The plant has \( DD \) alleles. Since \( D \) (dark brown) is expressed with \( DD \), the observable trait (phenotype) is dark brown seeds.

Answer:

dark brown seeds
