Answer:

1:The physical expression of a gene. (Characteristics).

Explanation:

Phenotype is how a gene is expressed. It is the 'appearance' or so called 'characteristics' of an organism resulting from its genotype.

For example:

The genotype is 1TT : 2Tt : 1tt

(T is for tall and t is for short)

The phenotype is 3Tall : 1short

The heterozygous allele is considered a Tall since the dominant allele is expressed.
