What does the phenotype of an organism depend on?
An organism’s phenotype results from two basic factors: the expression of an organism’s genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype.
What factors influence an organisms phenotype?
These attributes are known as the phenotype. Two factors that influence the phenotype are: (1) the specific genetic information of the individual (its genotype), and (2) environmental influences on the expression of the individual’s genetic potential.
What is a phenotypic expression?
Phenotypic expression is the result of a complex interplay between an organism’s genes and its environment. During growth and development, organisms undergo a programmed series of phenotypic changes. The ability to vary phenotypic expression in response to environmental conditions is known as “phenotypic plasticity.”
How does the phenotype depend on its genes?
Genotype versus phenotype. An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. For example, differences in the genotypes can produce different phenotypes.
How are phenotypes expressed?
Phenotype is defined as an organism’s expressed physical traits. Phenotype is determined by an individual’s genotype and expressed genes, random genetic variation, and environmental influences. Examples of an organism’s phenotype include traits such as color, height, size, shape, and behavior.
What determines phenotype?
An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What regulates phenotypic expression?
Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.
How are phenotypes determined?
What role does DNA play in phenotypic expression in organisms?
Genotype is the full extent of an organism’s heredity information, whereas phenotype refers to an organism’s observable characteristics, such as structure and behavior. DNA, or deoxyribonucleic acid, is responsible for genotype and partially responsible, along with the environment, for phenotype.
