Genetics: The study of various aspects of genes like their structure, location, function is called genetics.
Gene: The small portion of chromosome which is responsible to transfer the parental characters from one generation to another is called gene.
Heredity characters: Those characters which are able to transfer from generation to generation are called heredity characters. They are also called parental characters.
Father of genetics: Gregor john Mendel. He did his experiments on pea plant (Pisum sativum). Mendel chose pea plant because:
|Character||Dominant character||Recessive character|
|Height of plant||Tall (T)||Dwarf (t)|
|Shape of the seed||Round (R)||Wrinkled (r)|
|Color of the seed||Yellow (Y)||Green (y)|
|Color of the seed coat||Brown (B)||White (b)|
|Shape of pod||Inflated (I)||Constricted (i)|
|Color of pod||Green (G)||Yellow (g)|
|Position of flower||Axial (A)||Terminal (T)|
Hybrid: Those organisms which have heterozygous pair of genes are called hybrids.
Mendel selected pea plant for his experiment for the following reasons:
Yes, Mendel's law applies to human beings too. But while applying the law to the human beings, many problems would rise.
Two probable causes that Mendel did not do is experiment in frog instead of pea plant are as follows:
The characters which are transferred from parents to the offsprings are called hereditary characters. Genes transfer various characters from parents to offsprings.
The branch of biology concerned with the study of the mechanism of heredity and variation is called Genetics. Gregor Mendel is known as father of genetics.
