An organism's traits are determined by its genotype, which is coded in DNA located in genes. Different forms of genes are called alleles.
The environment can influence an organism's traits over time through natural selection and mutation.
1. Natural selection: Natural selection is the process by which certain traits become more or less common in a population based on their fitness or ability to survive and reproduce. This means that individuals with advantageous traits are more likely to pass on their genes to the next generation, leading to a change in the frequency of those traits in the population over time.
2. Alleles: Alleles are different forms or variations of a gene. Genes are segments of DNA that contain the instructions for producing specific traits. Within a population, there can be multiple alleles for a particular gene, each with its own effect on the expressed trait.
3. Phenotype: Phenotype refers to the observable physical and functional characteristics of an organism, which are a result of the interaction between the organism's genotype and its environment. It includes traits such as eye color, height, and behavior.
4. Evolution: Evolution is the process of change in species over time. It occurs through the gradual accumulation of small genetic changes in populations, which can result in the emergence of new species or the modification of existing ones.
5. DNA: DNA, or deoxyribonucleic acid, is the molecule that contains the genetic instructions for the development and functioning of all living organisms. It is composed of a sequence of nucleotides that encode the information necessary for the synthesis of proteins, which play a central role in determining an organism's traits.
6. Genes: Genes are specific segments of DNA that contain the coding sequence for a particular trait or function. They are responsible for the inheritance and transmission of genetic information from one generation to the next.
7. Mutation: Mutation is a random change in the genetic material, such as a change in the DNA sequence of a gene. Mutations can lead to new alleles or variations in existing alleles, which can ultimately contribute to the diversity of traits within a population.
