Organisms have to reproduce (makebabies) so their species can survive.
If a species stopped reproducing , it     would eventually go extinct.
Definition:There are         of reproduction:   reproduction           reproduction.

asexual reproduction: only one parent;offspring genetically identical to parent          Examples of asexual reproduction
asexual reproduction: only one parent;offspring genetically identical to parent          Example of asexual reproduction
The                         of asexual reproduction is      that it is                                                    ...

Fertilization:
(sperm or eggs)  46 is thechromosome number for  humans
: all
fertilization (the uniting of the gametes)        creates a unique offspring.
The offspring gets half of its genes fromeach parent but it is a unique individual.

ZygoteFormation, Growthand Differentiation:
The following is how multi-cellular organisms reproduce:
sperm and eggcombine, results in a zygote (a fertilized                 egg).
(a fertilized egg) has 46         chromosomes (for humans).  Azygote
The zygote undergoes acalled         . The cells divide and divideand divide and divide….without growing in               ...
from steps A to E, the cells are               . None of the cells have aspecialized function. At steps F and G           ...

A development question like this may be           on the regents
You must know the steps of development for the                   regents!
You must know the steps ofdevelopment for the regents!

HumanReproduction    andDevelopment
You must know the humanreproductive systems and what each    part does for the regents….
For the male reproductive system: you onlyneed to know that organ “X” is           .      The testes                      ...
The female reproductive system ismore complicated than the male’s
You have know a lot more….
