Multiple Choice
In fundamental genetics, the genotype is best defined as the what of an organism?
A
Genetic makeup (the set of alleles an organism carries)
B
The complete set of proteins expressed by an organism at a given time
C
Environmental influences that shape an organism’s development
D
Observable characteristics of an organism (its traits)
Verified step by step guidance1
Understand that the term 'genotype' refers to the genetic constitution of an organism, specifically the set of alleles it carries for particular genes.
Recognize that genotype is distinct from phenotype, where phenotype refers to the observable traits or characteristics of an organism.
Recall that genotype involves the DNA sequence and allelic combinations inherited from the parents, which determine potential traits.
Note that genotype is not about the proteins expressed at a given time (which relates to gene expression) nor environmental influences, but strictly the genetic information.
Conclude that the best definition of genotype is the 'genetic makeup' or the set of alleles an organism carries.
