Explain the difference between genotype and phenotype. Be sure to mention the role of environmental influences.
What will be an ideal response?
A genotype is one's genetic heritage, the actual genetic material that determines characteristics. A phenotype is one's observable characteristics. The phenotype is influenced by the genotype but also by environmental factors. The activity of genes (genetic expression) is affected by their environment. For example, hormones that circulate in the blood make their way into the cell where they can turn genes on and off. The flow of hormones, too, can be affected by environmental conditions, such as light, day length, nutrition, and behavior.
