HEREDITY
The most obvious outcome of the reproductive process still remains the generation of individuals of similar design. The rules of heredity determine the process by which traits and characteristics are reliably inherited. Let us take a closer look at these rules.

Inherited Traits
What exactly do we mean by similarities and differences? We know that a child bears all the basic features of a human being. However, it does not look exactly like its parents, and human populations show a great deal of variation.

EVOLUTION
We have noted that there is an inbuilt tendency to variation during reproduction, both because of errors in DNA copying, and as a result of ****ual reproduction. Let us now look at some consequences of this tendency.
Evolution is the sequence of gradual changes that take place in primitive organisms, over millions of years, in which new species are produced.

Gregor Mendel - The Father of Genetics
Acquiring characteristics or traits from one generation to the other is nothing but inheritance. Here, both parents contribute equally to the inheritance of traits.
It was Gregor Mendel, known as the Father of Genetics, who conducted immense research and studied this inheritance of traits.

Rules of Inheritance
Gregor Johann Mendel was a scientist who is recognized as the Father and Founder of genetics. Mendel conducted many experiments on the pea plant (Pisum sativum) between 1856 and 1863.
He studied the results of the experiments and deducted many observations. Thus, laws of inheritance or Mendel’s laws of inheritance came into existence.

All the above-mentioned topics are described in an interactive and efficient manner so that the students could easily understand them.

Lyrics:
Days like this I want to drive away
Pack my bags and watch your shadow fade
You chewed me up and spit me out
Like I was poison in your mouth
You took my light, you drain me down
That was then and this is now
Now look at me

Chorus:
This is the part of me
That you’re never gonna ever take away from me, no
This is the part of me
That you’re never gonna ever take away from me, no
Throw your sticks and your stones
Throw your bombs and your blows
But you’re not gonna break my soul
This is the part of me
That you’re never gonna ever take away from me, no

I just wanna throw my phone away
Find out who is really there for me
You ripped me off, your love was cheap
Was always tearing at the seams
I fell deep, you let me down
But that was then and this is now
Now look at me

Chorus:
This is the part of me
That you’re never gonna ever take away from me, no
This is the part of me
That you’re never gonna ever take away from me, no
Throw your sticks and your stones
Throw your bombs and your blows
But you’re not gonna break my soul
This is the part of me
That you’re never gonna ever take away from me, no

Bridge:
Now look at me I’m sparkling
A firework, a dancing flame
You won’t never put me out again
I’m glowing oh whoa
So you can keep the diamond ring
It don’t mean nothing anyway
In fact you can keep everything
Yeah yeah, except for me

Chorus:
This is the part of me
That you’re never gonna ever take away from me, no
This is the part of me
That you’re never gonna ever take away from me, no (away from me)
Throw your sticks and your stones
Throw your bombs and your blows
But you’re not gonna break my soul
This is the part of me
That you’re never gonna ever take away from me, no

This is the part of me (no)
(away from me) This is the part of me
Throw your sticks and your stones
Throw your bombs and your blows
But you’re not gonna break my soul
This is the part of me
That you’re never gonna ever take away from me, no
