What Is a Trait Generally speaking, the common meaning of the word "trait" is some distinctive, recognizable characteristic that can vary between objects. The scientific definition is similar, but more specific: in biology, a trait is a specific characteristic stored within the genetic material of...
In biology,heredityrefers to the passing of genetic factors from parents to offspring or from one generation to the next. The biological definition of heredity may also pertain to the association of a particular trait with the genetic constitution of an individual organism, rather than with environm...
each gene has specific instructions on how to make a protein. Proteins are composed of smaller building blocks, referred to asamino acids. Codons are a series of threenucleotidesthat are read in order from left to right to code for an amino acid. The nucleotides involved in this process are...
Selective breeding, the practice of mating individuals with desired traits as a means of increasing the frequency of those traits in a population. In selective breeding, the breeder attempts to isolate and propagate the genotypes (genetic constitutions)
A basic biology definition would be is that it is the study of living organisms. It is concerned with all that has life and living. (Ref.1) In contrast to inanimate objects, a living matter is one that demonstrates life. For instance, a living thing would be one that is comprised of ...
Survival of the fittest, term made famous in the fifth edition of On the Origin of Species by Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing. The term was later used
These calculations aid in the production of genetically engineered products as desired. Important Terms related toGenotypic Ratio Pure Line:It includes those organisms that have arisen through self-fertilization repeatedly, and remain homozygous for a specific trait. This trait is transferred to offspring...
Evolution is all about change over time, but what is the mechanism that causes these changes? Every living thing has everything about its construction encoded in a special chemical structure calledDNA. Within the DNA are chemical sequences that define a certain trait or set of traits. These se...
Physiognomy plays an important role in literature by allowing the audience or reader to identify characters who have hidden intentions or motives. In classrooms, especially to connect with students’ previous knowledge in biology, students will readily understand that sometimes inner turmoil can lead to...
The result of stabilizing is the over-representation in a specific trait. For example, the coats of a species of mice in a forest will all be the best color to act as camouflage in their environment. Other examples include human birth weight, the number of eggs a bird lays, and the den...
