Multiple Choice
In fundamental genetics, what is the definition of a phenotype?
A
A specific alternative form of a gene found at a particular locus
B
The complete set of DNA sequences (alleles) carried by an organism
C
A diagram that shows the inheritance pattern of a trait within a family across generations
D
The observable characteristics or traits of an organism resulting from the interaction of its genotype and the environment
Verified step by step guidance1
Understand that in genetics, the term 'phenotype' refers to the observable characteristics or traits of an organism.
Recognize that these traits result from the interaction between the organism's genotype (its genetic makeup) and environmental factors.
Differentiate phenotype from genotype, where genotype is the complete set of genes or alleles an organism carries, while phenotype is what you can actually observe.
Note that a phenotype includes physical traits like eye color, height, and behavior, which are influenced by both genes and environment.
Remember that the other options describe different genetic concepts: an allele is a specific form of a gene, the genotype is the full genetic makeup, and a pedigree is a family inheritance diagram.
