questions:
(I look like….
I’m as tall as my …

-
How do you think, are rules of inheritance the same to
plants and animals?
-
Today we will discuss the Mendel’s theory and by the end of
the lesson you will understand how people, plants and animals as

demonstration
Gregor Johann Mendel was a scientist who is recognized as
the Father and Founder of genetics was born in in
1822.
Mendel conducted many experiments on the pea
plant. He had
chosen pea plant because The pea plants were easy to grow and it
breeds in short
time.
Peas are naturally self-pollinating but can
also be cross-pollinated. He studies some
characteristics:

Grammar: Adjective
complement
An adjective complement is defined as a functional part of
a sentence that completes the meaning of, or complements, an
adjective or adjective phrase.
A noun
clause is simply two or more
words that function as a noun. It should have a subject and a verb,
and, since it takes the place of a noun, it’s a dependent clause
and cannot stand alone. A noun clause starts with the words “that,"
“how,” “if,” and the wh- words “what,” “when,” “why,” "who," and
"where."
A prepositional
phrase starts with a
preposition — such as “with,” “about,” “on,” or “in” — and is
followed by a noun, pronoun, noun phrase, pronoun phrase, or noun
clause.

Fill the
gaps:
Characters dwarf dominant recessive
generation
The
results of Mendel’s experiments on crossing a pure tall pea plant
with a pure short pea
plant:
In the first
generation, Mendel observed that all plants were tall. there were
no dwarf plants.
In
the second _____,
Mendel observed that 3 of the offsprings were tall whereas 1
was _____.
Similar
results were found when Mendel studied
other ______.
Mendel
observed that in the first generation, the characters of only one
parent appeared whereas, in the second generation, the characters
of the other parent also
appeared.
The
characters that appear in the first generation are
called _______
traits and
those that appear for the first time in the second generation are
called ______
traits.
(answers: generation dwarf
characters dominant recessive
)
