Multiple Choice
In fundamental genetics, an organism’s genotype is its:
A
Genetic makeup (the specific alleles it carries for one or more genes)
B
Observable physical or biochemical traits (its phenotype)
C
Set of environmental conditions that influence trait expression
D
Type of habitat or ecological niche where it lives
Verified step by step guidance1
Understand the definition of genotype: It refers to the genetic constitution of an organism, specifically the alleles it carries for one or more genes.
Recognize that phenotype is different from genotype; phenotype describes the observable physical or biochemical traits resulting from the genotype and environmental influences.
Note that environmental conditions and habitat do not define genotype; they influence how genes are expressed but are not part of the genetic makeup itself.
Identify that the correct description of genotype is the organism's genetic makeup, meaning the specific alleles present in its DNA.
Conclude that among the given options, the one that matches the definition of genotype is 'Genetic makeup (the specific alleles it carries for one or more genes)'.
