The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What is phenotype best described as?
The phenotype is best defined as the “observable characteristics that result from the expression of genes of an organism, which can largely be modulated by environmental or other conditions” .
How do you describe phenotype and genotype?
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.
What is phenotype and example?
A phenotype is a trait we can observe. Genes carry instructions, and the result of our body following those instructions (for example, making a pigment in our eyes), is a phenotypic trait, like eye color. Sometimes a trait is the result of many different genes, like the 16 genes responsible for eye color.
How do you express phenotype?
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.
Is the phenotype the letter or the character description?
A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele). phenotype = the physical appearance of a trait in an organism.
What is heterozygous example?
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
How do you use phenotype in a sentence?

What is the definition of phenotype quizlet?
phenotype. the physical appearance of an organism based on the genotype (genes) pure. obtained from a cross with hybrid organisms; homozygous.
What are 3 examples of genotype?
Examples of Genotype:
- Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …

How does a genotype become a phenotype?
Genotype & 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.
