MENDEL LAWS
During the 19th century, the Industrial Revolution was happening, and industries
were growing rapidly. For factories to function, they needed raw materials. Since
some countries did not have enough resources, they began to buy them from other
countries. Some even stole them. Over time, they realized they could colonize lands
in Africa and other places to get the raw materials they needed instead of buying
them, so the colonization period started.
During the colonization period, new species were discovered and fossils began to be
found. This made scientists wonder about the evolution of the species and how
offspring inherit traits ?
GREGOR MENDEL, an Austrian scientist, made a research to solve the question
HOW THE OFFSPRING INHERIT TRAITS ? through an experiment.
MENDEL’S EXPERIMENTS→
At first, Mendel considered experimenting with animals in his research. The
experiment consisted of crossing animal species to observe how they inherited traits.
However, he realized that using animals for the experiment would be really difficult
and time-consuming. That's why he decided to use peafs plants instead of animals in
his experiment.
Mendel grew pea plants and began
to observe their characteristics,
such as height of the plant,
position of the plant, colour of the
flower, shape of the peafs, shape of
the pod, colour of the peafs and clour of the pod. Then, through a process called
, pollination (where one peaf plant transfers its pollen to another plant), he mixed
different peaf plants. (Mendel kept the plants covered to prevent them from
pollinating each other naturally. Then, he pollinated them manually)
Mendel observed how traits changed in the offspring of the plants and noted
what traits they inherited. He repeated this process several times to study how
traits were inherited from one generation to the next.
The conclusions he got were three laws, the three MENDEL LAWS. He sent his
discoveries to CHARLES DARWIN, but although they didn’t speak the same
lenguaje, Darwin didn’t read them and his discovery was lost. Years later, some
scientists came to the same conclusions that Mendel had reached earlier. Thanks to
this, his work was remembered and his merit was finally recognized.
MENDEL LAWS:
(Mendel studied and observed 7 different characteristics but to explain his laws I am
going to use the characteristic of the COLOR OF THE peafs )
Mendel classified plants into two types: PURE RACE and HYBRIDS.
- Pure Race: Plants that crossed together consistently produced the same trait
over generations
- Hybrids: Offspring resulting from a cross between two pure race plants with
different traits.
MENDEL’S FIRST LAW
This law is also called the principle of uniformity .
