Heredity and Mutation - In the Subject field of the Natural Sciences Biology are terms that relate to Heredity and Mutation. What is the difference between heredity and mutation? Heredity is how information is based from one generation to the next; encoded in the DNA molecule. A mutation is a mistake that is made in the DNA. Most mutations have no affect, some are harmful, and a small number confer an advantage. Natural Selection works to eliminate the harmful and enhance the beneficial.

The following definition of terms related to the Heredity and Mutation:

1. Autosomal is a chromosomes outside of the sex chromosomes.
2. Dihybrid is a marriage by taking into account two different characteristics.
3. Agglutinin is a substance that can agglutinate red blood cells.
4. Aglutinogen is a red blood cell antigens that stimulate the formation of agglutinin. Used as the basis for the classification of human blood into types A, B, AB, and O.
5. The dominant phenotype is a characteristics that appears in F1, characteristics the win against a recessive characteristics.
6. Epistasis is an beralel gene interactions, with one covering the gene expression of other genes.
7. Phenotype is the appearance of characteristics as a result of interaction between the genotype with the environment.
8. Genotype is a characteristics that is determined by genes.
9. Haemophilia is a blood disease hard freeze.
10. Heterozygous is a genotype that composed of genes and alleles that are not the same, one dominant and the other recessive.
11. Kiasma is a connection there between homologous chromatids, where the exchange process in the event of crossovers.
12. Lethal is a gene that cause of death of the individual.
13. Monohibrid is a marriage by taking into account the different characteristics.
14. Mutagen is a chemical substance, biological or treatments that can increase spontaneous mutation.
15. Mutant is an organism mutate so different from other types.
16. Links is a gene that is adrift because it is located on an adjacent locus.
17. Crossing over is an emigration event from one chromosome to genes homologous chromosome as the locus apart. Occurs during meiosis.
