    the next step‚ to create a genetic pool. After evaluating the fitness of the individuals of the initial population‚ a new population is created. The creation of a new generation is performed basically in three stages‚ reproduction‚ crossover and mutation. The overall goal of this step is to obtain a new population with individuals which have high fitness values. In reproduction stage‚ the individuals are selected among the population depending on their fitness values i.e. individuals with

    Define gene mutation. (1) Define means to give the precise meaning of a word‚ phrase or physical quantity. Gene mutation is a change in the base sequence of an allele. The changed base sequence may produce a different amino acid sequence in the protein translated. The changed base sequence may not change the protein because of the degenerate nature of the genetic code. The expression of the mutated gene may or may not be beneficial to the organism. Substances that cause mutation are called mutagens

    Causative Mutations CF is caused by a mutation in the gene “cystic fibrosis transmembrane conductance regulator” (CFTR) on chromosome seven. 70% of all mutations in the gene involve the deletion of 3 nucleotides resulting in loosing the amino acid phenylalanine in position 508 ‚ naming this mutation ∆F508. There are over 1500 other mutations‚ however‚ that can produce CF. Most people have 2 functioning allele of the CFTR gene and CF develops when both are faulty. Consequences of mutation at cellular

    display melanism and the gene MC1R is responsible for pigment type. Specific mutations in this gene allow for all black jaguars. A change in the protein’s sequence‚ deleting 5 amino acids and changing one into MC1R protein‚ is responsible for this mutation rather than a genetic switch. Therefore‚ the ability of pigmentation to evolve without affecting other functions is due to the evolution of the MC1R regulation. MC1R mutations have been able to cause changes in cats and melanic plumage in birds. There

    well known theories and biological phenomena on the topic of ageing with critical evaluation in answering the title ‘How and why do we age?’ The first theory on why do us humans age is called ’The Somatic Mutation Theory of Ageing’. This theory (summarised) states that ageing is caused by mutations in our genes when they are copied incorrectly each
