It states that two alleles of a trait remain together in heterozygote without contamination but they separate or segregate at the time of gamete or spore formation or meiosis.

It states that out of two traits of the parents , only one trait appears inF1 generation. The trait which expresses in F1 generation is called dominant trait while hidden trait is called recessive trait.

The reason for Mendel's success are;

1. Pre-Mendalian experiments on heredity failed because they concentrated on inheritance of many characters at a time. Mendel focused on inheritance of a single character.

2. He used pure breeding plants which have two contrasting characters .There was no intermediate.

3. Mendel kept accurate records in crosses and even maintained exact number of seeds or plants produced.

4. He used self-pollinated plant in which undesirable cross pollination was totally...

Mendel's experiment produced the following results:

1. In all the seven traits, he found that the F1 generation resembled only one of the parents. He obtained same result in reciprocal cross. The trait expressed in F1 generation was called dominant and the one that remained hidden was known as recessive.

2. In F2 generation, both the parental forms reappeared.

3. The ratio of the dominant form to recessive was always 3:1 i.e, the dominant form was three times the number the recessive form.

4. In...

Krebs cycle includes series of reactions through which acetyl COA produced in oxidative decarboxylation of pyruvic acid is completely broken down to CO2 and H2O with uptake of O2 ands release energy in form of ATP. Krebs cycle is also called as citric acid cycle or tricarboxylic acid (TCA) cycle.
