What happens according to Mendelian inheritance?
(http://anthro.palomar.edu/mendel/mendel_1.htm Make sure your explanation refers to genotype,
phenotype, homozygous, heterozygous, dominant, recessive, and the Mendelian laws of
segregation and independent assortment)
How are genes passed on in humans and other sexually reproducing organisms?
(http://en.wikipedia.org/wiki/Meiosis Make sure your explanation refers to meiosis, DNA,
chromosome, chromatid, haploid, diploid, and recombination. Don’t worry about remembering
all of the names of the phases. This video should help you to understand the basic process
http://www.youtube.com/watch?v=kVMb4Js99tA and this can help you understand why meiosis
is important in sexually reproducing organisms

How does Mendelian inheritance increase genetic variation? (Think about it)
What are crossovers and how do they increase genetic variation? (You don’t need to read the
table on differences between egg and sperm production for this class or the information on
centimorgans. Read http://www.dnainheritance.kahikatea.net/crossover.html and think about it.
Can you answer the author of the websites question in the Grandparent/Child inheritance
diagram section?)
