The external layer of the human skin is called the epidermis and it replaces itself approximately every 27 days through shedding, which is known as exfoliation. Only this outer or surface layer of skin is replaced during the exfoliation process.
Gregor Mendel, the Moravian Augustinian monk who founded the modern science of genetics. Mendelian inheritance is a type of biological inheritance that follows the laws originally proposed by Gregor Mendel in 1865 and 1866 and re-discovered in 1900. These laws were initially very controversial.
The father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied 'trait inheritance', patterns in the way traits were handed down from parents to offspring.He observed that organisms (pea plants) inherit traits by way of discrete units of inheritance.rait inheritance and molecular inheritance mechanisms of genes are still a primary principle of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes.
