Question

there are two different alleles for flower color, p and p. the image shows a white sweet pea with a genotype of pp. what can you surmise from the labeled image? the genotype is heterozygous. white petal color is a recessive trait. white petal color is a dominant trait.

Explanation:

1. Analyze the genotype: The sweet pea has a genotype of pp, which is homozygous (two identical alleles). So the option about heterozygous is incorrect.
2. Recall dominant/recessive traits: A recessive trait is expressed when an organism has two recessive alleles (like pp). Since the white flower has pp and shows the white trait, white is likely recessive (dominant traits are expressed with at least one dominant allele, e.g., PP or Pp). The option saying white is dominant is wrong because a dominant trait would be expressed with Pp or PP, and having pp (two recessive) expressing white implies white is recessive. The last option is unclear but from the first two analyses, the correct surmise is that white petal color is a recessive trait.

Answer:

B. White petal color is a recessive trait (assuming the options are labeled as A, B, C, D with B being "White petal color is a recessive trait")
