Grade Level Expectations:
1)
Relate the continued
existence of any species to its successful reproduction and explain in writing
the factors that contribute to successful reproduction.
2)
Describe the structure,
location and function of chromosomes, genes and DNA and how they relate to each
other in the living cell.
3)
Illustrate and chart
the purpose, cell type (somatic and germ) and resulting chromosome count during
cell division in mitosis and meiosis.
4)
Identify the major
structures in human male and female reproductive systems and explain where
meiosis and gamete formation take place.
5)
Investigate and report
on the role of hormone production as it initiates and regulates the creation of
male and female germ cells from birth through adolescence and into adulthood.
6)
Compare and contrast
the events and processes that occur when a human egg is fertilized or not
fertilized.
7)
Demonstrate the
relationship of corresponding genes on pairs of chromosomes to traits inherited
by offspring.
8)
Describe in writing
the role of the germ cells in the formation of the human zygote and its
resulting 23 pairs of chromosomes, the 23rd of which determines gender and the
other 22 of which determine the characteristics of that offspring.
"Biology is the only science in
which multiplication means the same thing as division."
