1. what is the term for an observable trait of an organism?

phenotype
genotype
hybrid
allele

Explanation:

• Phenotype: Refers to the observable physical or biochemical characteristics of an organism, which are determined by its genotype and environmental factors. For example, eye color, height, and flower color are phenotypes.
• Genotype: Represents the genetic makeup of an organism, the set of genes it carries. It is not directly observable in the same way as the phenotype.
• Hybrid: An organism that has two different alleles for a particular trait (heterozygous), often resulting from crossing two different pure - bred (homozygous) parents.
• Allele: One of two or more alternative forms of a gene that arise by mutation and are found at the same locus on a chromosome.

Since the question asks for the term of an observable trait, the key - word is "observable". The phenotype is the observable trait, while the genotype is the genetic basis (not directly observable in the sense of physical traits without genetic testing), the hybrid is a type of organism based on allele combination, and the allele is a part of the genetic code.

Answer:

Phenotype
