All or part of the genetic constitution of an individual or group is called?

• A. Phenotype
• B. Genotype
• C. Genome
• D. Allele

Answer: (B)

Genotype is the genetic constitution—the specific genes and their variants you carry at each locus. It describes the combination of alleles an individual has, like BB, Bb, or bb for a given gene, which determines the range of traits that could be expressed. The phenotype is the observable trait that results from gene expression and environmental influences. The genome refers to the entire set of genetic material in an organism, not just the particular genes carried. An allele is one variant form of a gene. So all or part of the genetic constitution is captured by the term genotype.
