Gregor Mendel (1822-1884)
Mendel is known by many as the farther of modern genetics, possibly an
unlikely title for a man who grew pea plants as a hobby. Mendel, who was a
monk, conducted his studies of inheritance traits in pea plants within the
monastic gardens of the abbey of St. Thomas in Brno (Czech Republic). He
originally joined the monastery in order to further his education. Being the
son of a poor farming family, he would have otherwise been unable to access
higher education.
The monastery sent Mendel to study towards a teaching
degree at the University of Vienna; however, he was unsuccessful in a number
of exams and ultimately dropped out of university education. Returning to
the rugs monastery, he brought with him an enquiring mind and a desire to learn
about the natural world without being burdened by orthodox religious
explanations.
Between 1856 and 1863, he conducted a number of experiments using a
straightforward crossing technique, and he documented his findings in
exceptional detail. Mendel realised that when plants with different flower
colours were crossed, the offspring only carried the traits of one of its
parents, not a combination as he first expected. Mendel named the traits
that were visibly expressed in the hybrids as ‘dominant traits’ and those
that were not visible as ‘recessive traits’.
Mendel then continued his experiments by self-fertilising his hybrid
offspring. He discovered that there was frequently a 3:1 ratio of
characteristics for the second generation. For example for every three
plants with red flowers, one would be produced with white flowers. This
meant that a plant with the red flowering trait may also carry the recessive
white flowering trait, which although remains dormant, may be passed on to
offspring.
Following the success of his experiments, Mendel published his findings in
the ‘Journal of the Brno Natural History Society’ in 1866. Unfortunately,
his work received very little recognition, possibly because he was not a
renowned scientist and the scientific community never really noticed the
significance of a monks work.
After his publication, Mendel continued his
experiments within the grounds of the monastery. He took his experiments a
stage further by conducting animal experiments (breeding bees). He was able
to breed bees with the desired characteristic (very high honey production),
although it is said that these animals had to be destroyed because they were
very prone to stinging people within the monastery and the surrounding
village.
In 1868 Mendel was elected Abbot of the monastery and he did not continue
with any significant scientific investigation after this time. Mendel died
in 1884, without receiving any significant scientific accolade for his
accomplished works. It was not until 1900 that the Dutch botanist Hugo De
Vries rediscovered Mendel’s work. By the 1920’s Mendel’s work had been
linked to the Darwinian theory of Evolution to explain the variation in gene
frequency of ‘Mendelian pairs’ of characteristics within a particular group
or populous over succeeding generations.
The terms ‘recessiveness’ and ‘dominance’, which were coined by Mendel are
still used within the field of genetics today. Similarly Mendelian genetics
is widely studied at all academic levels. Mendel’s influence on modern
genetics cannot be over-stated. It is known that many diseases can be
inherited. Even looking to the plants that begun his study of hereditary, we
now see many varieties are ‘engineered’ in laboratories to exhibit certain
desired characteristics. The title ‘father of modern genetics’ seems well
deserved.

Genetically gifted for financial wizardry?
Before heading out into the world to beg people for money Geschlossene Fonds, there are things to be done on your end. First of all, get your credit in order.

Genetic inherited back ache?
Back ache can be cured if you are using the right kind of water bed Wasserbetten for sleeping. This is because, during sleeping, the bed will influence the pressure of your body. An unevenly balanced pressure will restrict you from sleeping properly. You will get pain on the back of your body.
If the bed is not proper, the body weight will not be supported properly. Then you will experience a pain due to uneven body weight. This pain throughout the night will end up in backache.
The first place most people turn to is the bank. Every bank has options for people looking to start their own business. Hook yourself up with a good banking representative and they will be able to lay all the cards on the table and figure out your best options and what they can offer based on your credit history.
