Which of the following is the correct definition for a phenotype? 1:The physical expression of a gene. (Characteristics).

2:The expression of one of your parents traits.

3:The set of genes in our DNA which is responsible for a particular trait.

1-physical expression of a gene

Explanation:

remember:

Phenotype= Physical appearance (e.g blue eyes)

Genotype=Gene (e.g gene for cancer)

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.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
