Multiple Choice
In the context of the fundamentals of genetics, the phenotype of an individual is best defined as which of the following?
A
The DNA sequence of a single gene expressed in all cells regardless of conditions
B
The complete set of genes (alleles) carried by an organism
C
The observable traits of an organism resulting from the interaction of its genotype and the environment
D
The set of chromosomes an organism inherits exclusively from its mother
Verified step by step guidance1
Understand the key terms: 'genotype' refers to the genetic makeup or the set of alleles an organism carries, while 'phenotype' refers to the observable characteristics or traits of the organism.
Recognize that the phenotype is not just the DNA sequence or the set of genes alone, but rather the traits that result from how those genes are expressed and interact with environmental factors.
Recall that the genotype provides the potential for certain traits, but the environment can influence how these traits are manifested, leading to the phenotype.
Eliminate options that describe only genetic information without considering expression or environmental influence, such as the DNA sequence or the set of chromosomes inherited.
Conclude that the best definition of phenotype is the observable traits of an organism resulting from the interaction of its genotype and the environment.
