Multiple Choice
In the context of fundamentals of genetics, what is the phenotype of an organism?
A
The complete set of alleles an organism carries at all loci
B
The observable characteristics of an organism resulting from the interaction of its genotype and environment
C
The process by which DNA is copied during the cell cycle
D
The genetic makeup of an organism as determined solely by its DNA sequence
Verified step by step guidance1
Understand that the term 'phenotype' refers to the observable traits or characteristics of an organism, such as height, eye color, or blood type.
Recognize that phenotype results from the interaction between an organism's genotype (its genetic makeup) and environmental factors, meaning it is not determined by genes alone.
Differentiate phenotype from genotype: genotype is the complete set of alleles an organism carries, while phenotype is how those alleles are expressed visibly or functionally.
Note that phenotype is not related to the process of DNA replication or copying during the cell cycle, which is a separate biological process.
Conclude that the correct definition of phenotype is 'the observable characteristics of an organism resulting from the interaction of its genotype and environment.'
