Begin by understanding the basic definitions of the terms provided: Chromosome, Allele, Phenotype, and Genotype.
A Chromosome is a structure within cells that contains DNA, which is organized into genes. Each chromosome carries many genes.
An Allele is a variant form of a gene. Alleles are responsible for the variations in traits, such as eye color. For example, the allele for brown eyes is a specific sequence of a gene that determines this trait.
Phenotype refers to the observable characteristics or traits of an organism, such as eye color, which result from the interaction of its genotype with the environment.
Genotype is the genetic makeup of an organism, consisting of all the alleles present in its DNA. It determines the potential traits an organism can express.
