Question 1

Genotypes - representing alleles

Answer 1

-Genotype: the genetic composition of an organism at one particular gene locus (represented using letter symbols)
-In diploid organisms, the genotype is typically written as a pair of alleles.

Question 2

Phenotypes - expressed trait

-Phenotype: the observable physical, behavioural or biochemical characteristics of an organism that are the result of gene expression and the environment.
-An organism’s phenotype is influenced both by its genotype and by the environment in which it lives, and is therefore susceptible to change over time.
