Verified step by step guidance1
Understand the term 'genotype': In genetics, the genotype refers to the genetic makeup of an organism, specifically the alleles (versions of a gene) that an individual possesses.
Differentiate between genotype and phenotype: The phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.
Identify the correct description: The genotype is concerned with the genetic information that is inherited from the parents, not the physical appearance or observable traits.
Consider the role of environment: While the environment can influence the expression of traits, it does not change the genotype itself.
Conclude with the correct choice: The genotype of a child is best described as the genetic makeup of the child, which includes all the genes inherited from both parents.
