  • Phenotype: Understanding Observable Traits & Genotype
    The external appearance of an organism as determined by what alleles are present is called phenotype.

    Here's a breakdown:

    * Genotype: The genetic makeup of an organism, represented by the specific alleles it carries for a trait.

    * Phenotype: The observable characteristics of an organism, including its physical appearance, behavior, and biochemical properties.

    Example:

    * Genotype: A person might have the genotype "Bb" for eye color, where "B" represents the brown eye allele and "b" represents the blue eye allele.

    * Phenotype: The person would have brown eyes because the brown eye allele (B) is dominant over the blue eye allele (b).

    So, the phenotype is the expression of the genotype.
