A spectrometer is an tool commonly used by astronomers which splits the light collected by a telescope into its colors.This allows astronomers see the details in the light from space. spectrometer is an tool commonly used by astronomers which splits the light collected by a telescope into its colors.
This is an emerging area of study, developing from Mendelian genetics through to the modern science, which can now accurately track genetic histories of populations. Examples of Gene Flow: Genetic heritage mapping
A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. For example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes. An allele is found at a fixed spot on a chromosome. Chromosomes occur in pairs so organisms have two alleles for each gene â one allele in each chromosome in the pair.
