O Punnett square
O gene
phenotype
O genotype

Answer 1

An observable trait in an organism is referred to as the phenotype. It is the expression of genes in an individual, resulting in visible physical characteristics and behaviors.

Step-by-step explanation:

An observable trait in an organism is referred to as the phenotype. The phenotype is the expression of genes in an individual, which includes visible physical characteristics and behaviors.

For example, if we consider the eye color of humans, the gene for eye color has different variants or alleles, such as blue, brown, or green. The phenotype would be the actual eye color, which could be blue, brown, or green.

In genetics, the genotype represents the combination of alleles or genes an individual possesses. The Punnett square is a tool used to predict the possible genotypes and phenotypes of offspring based on the genotypes of the parents.
