What is the connection between genotype and phenotype?
Terms in the vocabulary:
Genotype: An organism’s genetic makeup, including all of its genes.
Phenotype: An organism’s observable physical and behavioral characteristics that result from the interaction of its genes and its environment.
A gene is a DNA sequence that codes for a specific protein or RNA molecule and is the unit of heredity passed down from generation to generation.
Allele: A variant form of a gene that resides on a specific chromosome.
Dominant: A trait or allele expressed in an organism’s phenotype regardless of the presence of another allele.
Recessive: A trait or allele expressed in an organism’s phenotype only when two copies of that allele exist.
Homozygous: Possessing two identical alleles for the same gene.
Heterozygous: Possessing two different alleles for the same gene.
Punnett square: A diagram used to predict the genotypes of offspring produced by a cross between two individuals.
A pedigree is a chart showing the inheritance pattern of a specific trait or disease in a family.
The chapter’s title is “From DNA to Phenotype: Genotype to Phenotype.”
The relationship between genotype and phenotype is that an organism’s phenotype is determined by the expression of its genes, which comprise its genotype. Gene expression is the process by which this occurs. It includes the transcription and translation of genes into proteins and the regulation of gene expression by various mechanisms. Gene expression eventually results in the developing of an organism’s physical and behavioral characteristics, which comprise its phenotype.
