Quizplus · Accepted Answer

Genotype refers to an individual's genetic makeup, while phenotype refers to the physical expression of that genetic makeup. Therefore, genotype is manifested in phenotype.

Answer: A 
 Environmental factors such as temperature, humidity, and nutrition can have an impact on how genes are expressed, leading to changes in an individual's phenotype.

Answer: D 
 Variation refers to differences between individuals, and these differences are lost when individuals die. Therefore, variation dies with individuals.

Answers C and E are both incorrect. Phenotypic variation is observable, just as genetic variation can be observed through techniques such as DNA sequencing. Phenotype is not seen physically in the genotype, as genotype refers to an individual's genetic code rather than their physical appearance.
