Question

What does an organism's phenotype describe?

Answer 1

Answer:

B

Explanation:

The allelic combination of the organism is known as its genotype. The genotype is responsible for determining the traits (phenotype) of the organism. However, these traits are not solely determined by the genotype but rather the interaction between the genotype and the environment in which the organism exists.

Answer 2

Answer: B. the physical appearance of a trait

Explanation:

The allelic combination of an organism is called as genotype. The expression of any one of the alternative allele in an organism will lead to the expression of a particular trait in organism's morphology, physiology, and behavior. The expression of these traits are observable in an organism. The expression of such observable traits is called as phenotype.

On the basis of the above explanation, B. the physical appearance of a trait  is the correct option.
