Question

in a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fruit taste trait has two alleles. the allele for sour fruit (f) is dominant over the allele for sweet fruit (f). a certain muskmelon plant from this group has sour fruit. based on this muskmelon plants phenotype for the fruit taste trait, which of the following could be its genotype for the fruit taste gene? select all that apply. ff ff ff

Explanation:

Step1: Recall Dominant/Recessive Rules

A dominant allele (F) masks the recessive (f). So, sour (dominant) phenotype requires at least one F.

Step2: Analyze Each Genotype

• \( FF \): Two dominant alleles. Phenotype: Sour (correct, as F is dominant).
• \( Ff \): One dominant (F) and one recessive (f). F masks f, so phenotype: Sour (correct).
• \( ff \): Two recessive alleles. Phenotype: Sweet (incorrect, since plant has sour fruit).

Answer:

FF, Ff
