Guida verificata passo dopo passo1
Understand the key terms: 'Phenotype' refers to the observable characteristics of an organism, 'Genotype' refers to the genetic makeup, 'Chromosome' is a structure containing DNA, and 'Allele' is a variant form of a gene.
Identify the question's focus: The problem asks for the term that represents an organism's genetic makeup using two letters.
Recall that 'Genotype' is the term used to describe the genetic constitution of an organism, often represented by two letters indicating the alleles present (e.g., 'AA', 'Aa', or 'aa').
Recognize that 'Phenotype' is not the correct answer because it refers to traits that are expressed, not the genetic code itself.
Conclude that 'Genotype' is the correct term for the organism's genetic makeup represented by two letters, as it directly relates to the alleles inherited from the parents.
