Question

question 5
which of the following does not represent a phenotype?
a persons susceptibility to addisons disease
the height of a draft horse
the alleles in a mouse that control hair color
the extent to which an individual is shy

Explanation:

A phenotype is the observable physical or biochemical characteristics of an organism, resulting from the interaction of its genotype (genetic makeup) with the environment.

• A person's susceptibility to Addison's disease is a phenotypic trait influenced by genetic and environmental factors.
• The height of a draft horse is a measurable phenotypic characteristic.
• The extent to which an individual is shy can be observed and is a phenotypic trait (in the context of behavioral phenotypes).
• The alleles in a mouse that control hair color represent the genotype (genetic composition), not the phenotype (which would be the actual hair color).

Answer:

the alleles in a mouse that control hair color
