Distinguish between genotype and phenotype and explain how the environment may affect each
What will be an ideal response
Genotype is the actual DNA sequence or genetic makeup of an individual. Teratogens (agents that cause mutations) might damage the DNA and change the genotype. For instance, the DNA in an embryo exposed to ionizing radiation might be damaged, resulting in genes that malfunction. Phenotype is the physical expression of the genes. Height, hair color, and even enzyme activity are phenotypes. If the genotype is changed by the environment, the phenotype may also be changed. A single base change in DNA is responsible for the sickle cell phenotype. Phenotype is dependent on the environment in a variety of ways. One example is that a child might have the genotype "tall". If the child doesn't receive adequate nutrition, though, he still might not be as tall as his genes would ordinarily allow.
