What is a trait that we physically see called?
The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.

What the genes show or display the physical traits?
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
What trait can be hidden?
Recessive
Recessive— Traits that can be hidden in one generation and then appear in the next. Incomplete dominance—Traits in which the heterozygote shows a different phenotype from the homozygous dominant phenotype. Polygenic—Traits in which several genes contribute to the overall phenotype.
What is a physical trait example?
The color, shape and positioning of a person’s eyes are examples of physical traits that impact their overall appearance.
What are visible traits?
A visible trait is the final product of many molecular and biochemical processes. In most cases, information starts with DNA traveling to RNA and finally to protein (ultimately affecting organism structure and function).
Is the physical appearance of an organism?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. 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.
Where are my physical traits from?
Physical traits are observable characteristics determined by specific segments of DNA called genes. Multiple genes are grouped together to form chromosomes, which reside in the nucleus of the cell. Every cell (except eggs and sperm) in an individual’s body contains two copies of each gene.
Is the physical trait that is expressed in an individual?
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.
dominant trait. A form of the trait that appears in the hybrid generation. recessive trait. The form of a trait hidden, or masked, in the hybrid generation.
What is the trait that is hidden or masked and only sometimes appears?
an allele that can be masked, or hidden, by tht presence of another allele is classified as. recessive.
What do you mean by physical features?
