  6. 6. The Environmental component in the expression of a gene is called REACTION RULE. This, can vary a lot depending of the Traits. Thus in the expression of the Weight of an individual the Reaction rule is, or can be, very big but, for example, respect the ABO blood group system the Reaction rule is nonexistent. All of us belong to A blood group.

  8. 8. The most common or normal phenotype in a population. In the same way we also speak of wild type allele. In both cases it should be noted that the concept is relative because the silvester or predominant phenotype in one population can be rare in another. For example, in the Nordic Countries the silvester type human being white skinned, blond haired and blue eyed. While in Equatorial Guinea this phenotype would be inexistent or extremely rare.
  9. 9. white skinned, blond haired and blue eyed. white skinned, black or brown haired and dark eyed. black skinned, black and very curly haired and dark eyed. Podemos adjetivar un sustantivo y añadiendo la terminación al sustantivo. Observa los ejemplos.
  10. 10. This is Drosophila melanogaster the fruit fly
  11. 11. That Allele which manifests its phenotype in Heterozygosis. For example in peas we will consider the colour of the seed trait. The Allele determines the yellow colour of the seed and the allele determines the green colour of the seed. The individuals will show seeds of yellow colour and those which are genotype will have green colour in the seeds. Finally, the individuals which are Heterozygotics have yellow seeds which permit us to say that Allele is dominant respect .
  12. 12. The individuals will show seeds of yellow colour and those which are genotype will have green colour in the seeds. Finally, the individuals which are Heterozygotics have yellow seeds which permit us to say that Allele is dominant respect . The Allele that is silenced ( it is not expressed) in Heterozygosis get the name of Recessive Allele. In this example the allele is Recessive respect
  13. 13. COLOUR OF FLOWERS
  14. 14. Codominance appears when the hybrids show the two phenotypes of the Homozygotic. For example, we will consider the colour of the flowers of Mirabilis jalappa a plant called “ Four o’clock” in English and “Don Diego de Noche” in Spanish.
  15. 15. This plant is native of Mexico and was brought to Spain by the Conquerors. Its name refers to the flowers in the form of a bell-shape tube perfumed and showy. They open at night because they are pollinated by moths of the family Sphingidae that have a very long proboscis.
