An explanation of the results of Gregor Mendel’s research into the heredity of the common pea plant. How he cross bred pure bred plants with purple and white flowers; the results of this cross breeding programme in the first generation; how the self pollination of the first generation led to the offspring in the second generation developing purple and white flowers in the ratio of three to one.
An introduction to the work of the father of genetics, the 19th century monk Gregor Mendel; how he set up experiments to investigate the heredity of the common pea plant; an explanation of the seven traits he decided to investigate; the meaning of ‘trait’ and revision of phenotypes and genotypes; opposition to his conclusions; a summary of the 19th century hypothesis of ‘blending inheritance’.
An explanation of the principles of Mendelian genetic inheritance; patterns of genetic inheritance introduced using Punnett squares; an explanation of genetic inheritance of brown/blue eye colors; an introduction to alleles and gene variations; ‘phenotypes’ and ‘genotypes’; dominant and recessive alleles; probability of being born with brown eyes if parents have the genotypes ‘BB and bb’.
The difference between inheritance and evolution; how inheritance describes traits that you inherit from your parents; how evolution describes inherited traits over time through successive generations; common traits that you could inherit from your parents such as blue eyes, ‘hitchhikers’ thumbs or a ‘dimpled’ chin; some inherited traits including some ‘disabling’ conditions.
