2. REPRODUCTION sex cells = gametes they differ from other cells
they content only the half number of cell parts
by the fusion of two „ half“ gametes >
a new full-fledged cell arises = zygote
a new individual grows from the zygote

3. REPRODUCTION
if gametes contained the same number of organelles as other cells
> a double zygote would be formed > an organism with double cells
therefore gametes are created by a special division, called reduction division

4. REPRODUCTION important for sexual reproduction:
in the nucleus of the zygote there occurs a new combination
the result is a unicellular base of an organism similar to parents
but also with new qualities

5. REPRODUCTION heredity = genetics
the science dealing with heredity and variability of living systems
the founder of genetics - J.G. Mendel
carriers of genetic information are nucleic acids

6. REPRODUCTION nucleic acids: DNA it has an important quality:
it can copy itself = replicate
it is located in the chromosome
chromosome is in eukaryotic cell in the nucleus

karyotype is
a set of all
chromosomes
in the nucleus
