(DNA) of the
offspring compere
to the parents?
The offspring is _____________________ to
the parent
The offspring is __________________ to one or
both parents but NOT __________________ to
either.
Parent makes a ______________ of its
How does it
occur?
SEXUAL REPRODUCTION
•
The offspring receives _____________ of their
genetic information so the offspring has the
genes from one parent and ____________ of
________________________ DNA as the
their genes from the other parent.

•
The ________ (female gamete) contributes
___________ of the genetic information to the
offspring and the _________ (male gamete)
contributes the other _______ of the genetic
info to the offspring when the two sex cells join
during _________________________

Types of Asexual Reproduction to know:
______________________: Organism (such as an amoeba)
dividing in half to form two
new identical organisms. The
cytoplasm and the nucleus
equally divides
____________________: Organism (such as a yeast cell)
dividing into two cells that
are different in size but
genetically alike. The
nucleus divides equally but
the cytoplasm divides unequally.
______________________: Mold spore cells are released
and can develop into a new
individual _________________________________: Plants grown
from the breaking off of leaves, stems or roots
