Phenotype and Genotype
Q1: What is Phenotype?
Answer:
Phenotype refers to the external appearance of an organism. It is not inherited from parents to offspring.
Q2: What is Genotype?
Answer:
Genotype represents the genetic composition of an organism, it is the combination of alleles at a gene locus. It is inherited from parents to offspring.
Q3: Can organisms with the same Phenotype have different Genotypes?
Answer:
Yes, organisms with the same Phenotype may or may not have the same Genotype. Different Genotypes can result in the same Phenotype , as seen in the example of pea plants with Genotypes TT and Tt both being tall.
Q4: How are Phenotypes determined?
Answer:
Phenotypes are determined by observing the organism and affected by both genetic factors (genes) and environmental conditions. Phenotypes can change over time.
Q5: How are Genotypes determined?
Answer:
Genotypes can be determined by using biological methods such as polymerase chain reaction (PCR).
Q6: Is the Genotype visible?
Answer:
No, the Genotype is not visible as it represents the genetic material inside the body. It cannot be directly observed but can be inferred from the expression of the Phenotype and through genetic analysis techniques. The Phenotype , on the other hand, is visible as the external appearance of an organism.
Difference Between Phenotype and Genotype
Difference Between Phenotype and Genotype: Phenotype and Genotype are two terms used in Genetics. Genetics is a branch of science that deals with genes, heredity, and genetic variations. These terms are given by Wilhelm Johannsen in 1909. The concepts of Phenotype and Genotype are further included in The Genotype Conception of Heredity in 1911. The major difference between Genotype and Phenotype is that Genotype is the genetic makeup of an organism while the Phenotype is the external physical appearance of an organism.
