Multiple Choice
In the fundamentals of genetics, a genotype refers to what?
A
The observable characteristics (traits) expressed by an organism
B
The genetic makeup of an organism, specifically the alleles it carries for one or more genes
C
The set of environmental conditions that influence trait development
D
The physical location of a gene on a chromosome
Verified step by step guidance1
Understand that in genetics, the term 'genotype' refers to the genetic constitution of an organism, specifically the alleles it carries for particular genes.
Differentiate genotype from phenotype, where phenotype is the observable characteristics or traits expressed by the organism.
Recognize that genotype is about the inherited genetic information, while phenotype results from the interaction of genotype with the environment.
Note that genotype does not refer to environmental conditions or the physical location of genes on chromosomes, but rather the specific allelic composition.
Summarize that the genotype is essentially the set of alleles an organism has, which can be represented as pairs of letters (e.g., AA, Aa, or aa) for a given gene.
