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 is a genotype and how does it determine the phenotype?
Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). … In a narrow “genetic” sense, the genotype defines the phenotype.
How is an individual’s phenotype determined?
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 factors contribute to an individual’s 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 an example of a phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What is the process of getting from DNA to phenotype?
Phenotype, such as the color of hair and eyes, is expressed in part through the processes of transcription and translation. In transcription, the cell copies the gene-encoded information to the molecule messenger RNA (mRNA).
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What are the two main factors that determine an organism’s traits?
To summarize, two things determine the traits an organism has: its genotype and the dominance or recessiveness of the alleles it has.
What do genotype and phenotype have in common?
Genotype and phenotype are two fundamental terms in the science of genetics. … An organism’s genotype is the set of genes in its DNA responsible for a particular trait. An organism’s phenotype is the physical expression of those genes.
