Summary Introduction
Introduction:
The evolution is the process of the change of the characteristic features along with the genes over the consecutive generations. The evolution has resulted in the diversification of the species all over the world. Natural selection is responsible for the mechanism of evolution.

There are 2 alleles of this gene - the dominant B and the recessive b. DNA analysis shows that black individuals have either a BB or Bb genotype and that white individuals have a bb phenotype. However, you have discovered that a small percentage of White individuals have either a BB or Bb genotype. Explain two reasons that could explain this apparent anomaly. They have a BB or Bb genotype but a white phenotype.arrow_forward
