What Is the Definition of Gene in Biology? In biology, a gene is a segment of DNA located on chromosomes that produce protein. Genes also exist as alleles of which you need two to produce a certain trait in offspring. You get alleles from both parents that determine your genetic traits. ...

The segment of a DNA molecule which codes for a specific protein or polypeptide is called a gene.
Gene Pools: The branch of biology that deals with the transmission and behavior of genes is called genetics. There are various branches of genetics, including population genetics and molecular genetics. Answer and Explanation:1 In geography a gene pool is the sum total of all the genetic informat...
Gene mapping is the science that is used to identify and record the exact location of genes as well as the distance between them on a chromosome. This technology offers evidence of whether a disease that exists in a person, that is transmitted from a parent to the child, in lin...
Genome-scale data have already served to fundamentally clarify the role of gene flow during (and after) speciation, although we predict that the differential propensity for speciation among phylogenetic lineages will be one of the most exciting frontiers for future genomic investigation. We propose ...

There are four fundamental evolutionary forces that can influence the change of these traits, namely mutation, genetic drift, gene flow, and natural selection. Genetic drift, also known as random drift or random genetic drift, is the evolutionary mechanism whereby random fluctuation in allele ...

A gene is the basic unit of heredity. Genes are made of DNA that eventually makes functional molecules named proteins. The genetic information that will pass to the next generation is contained in the DNA of genes. Genes are part of chromosomes. Humans have two copies of each gene (and ...
