Question

which describes the relationship between a genotype, a phenotype, and an organism’s experiences?
a genotype is an organism’s allele combination. a phenotype is the physical appearance of a trait in an organism, which may be influenced by the organism’s experiences.
a genotype is an organism’s allele combination, which may be influenced by the organism’s experiences. a phenotype is the physical appearance of a trait in an organism.
a phenotype is an organism’s allele combination. a genotype is the physical appearance of a trait in an organism, which may be influenced by the organism’s experiences.
a phenotype is an organism’s allele combination, which may be influenced by the organism’s experiences. a genotype is the physical appearance of a trait in an organism.

Explanation:

To solve this, we recall the definitions: Genotype is the allele combination (genetic makeup), Phenotype is the physical trait expression. Experiences can influence phenotype (e.g., environment affecting appearance).

• Option 1: Correctly defines genotype (allele combo) and phenotype (physical trait, influenced by experiences).
• Option 2: Incorrectly says genotype is influenced by experiences (genotype is genetic, not experience - based).
• Option 3: Mixes up genotype and phenotype definitions.
• Option 4: Also mixes up definitions and incorrectly attributes experience influence to phenotype's allele combo (wrong).

Answer:

A. A genotype is an organism’s allele combination. A phenotype is the physical appearance of a trait in an organism, which may be influenced by the organism’s experiences.
