population it is a part of. This will be done by tracking how allele frequency is dependent upon the core principles of natural selection. Pre simulation Mutation is a change in DNA. An organism’s DNA affects all aspects of its life. An Allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. Allele frequency is a measurement that determines how frequent the allele expression of a particular gene arises in a population. In your

Although homologous chromosomes contain the same genes‚ they can have different alleles of the same gene. An allele refers to one of plenty of alternative forms of the same gene. For example‚ a set of homologous chromosomes explain eye color. One of the chromosomes genes explains blue eyes‚ and the other one explains brown eyes. This is the

It has a number of characteristics: It is a triplet code- three bases code of an amino acid It is a degenerate code- All amino acids bar one have more than one code Some codes don’t code for amino acids

Elephants Growing Smaller or No Tusks at All As you can see from the title‚ the evolutionary topic I chose was Elephants. Now‚ it is not just the elephant its self I will be ranting on about‚ but the fact that‚ “In the last 150 years‚ the world’s elephant population has evolved much smaller tusks” (Chris et.al 2007). If not smaller tusks‚ then they have actually been growing no tusks whatsoever. Now why on earth would elephants start to evolve this way? Tusks are such an important aspect to an

BLUEPRINT OF LIFE: CHAPTER 2 GENETICS Gregor Mendel’s experiments helped advance our knowledge of the inheritance of characteristics 2.1 GREGOR MENDEL AND THE BIRTH OF GENETICS Gregor Mendel (1822-84) – ‘the father of genetics’ Born in Austria He was an Augustinian monk He worked as a teacher and as an investigator He observed the growth of peas He recorded the ratios of characteristics that appeared in the offspring His discovery stated he observed a pattern in the inheritance of characteristics

8.3 POLYMORPHISMS DETECTED BY PCR Without a doubt‚ the polymerase chain reaction (PCR) represents the single most important technique in the field of molecular biology today. What PCR accomplishes in technical terms can be described very simply — it allows the rapid and unlimited amplification of specific nucleic acid sequences that may be present at very low concentrations in very complex mixtures. Within less than a decade after its initial development‚ it has become a critical tool for all practicing

Mendel’s principles of inheritance suggests that the inheritance of the traits we possess take place at a molecular level and is brought about by the interaction of two ‘determinants of inheritance’‚ also known as alleles. Secondly‚ Mendel suggested that in the event that two different alleles come together‚ one is expressed while the other is not. The chromosome theory of inheritance describes the chromosome s the basic factor of inheritance. This theory coincides with Mendel’s principles of inheritance
