Heredity Assignment
Part 1:
 Describe his work and why it’s so significant? How did he investigate heredity? Note: they
still call it “Mendelian inheritance” 
o Bio text - pp. 263-266 and summary of his work on the top of p 272

How are meiosis and alleles related– what are they? How are they passed on? What is the
chance you’ll pass on genes you got from your mother? From your father?
o Bio text - probability p 267 – defined on p 265- also read about segregation

What is Dominant/Recessive?
o Bio text - p 264-265 “Genes and Dominance”

Define: Heterozygous “Rr”, Homozygous (Homozygous recessive “rr” , Homozygous
dominant “RR”)


Describe how Punnett Squares are used. Provide example.
o Bio text pp 268-269
Part 2: Beyond Mendel’s ideas…….some recent studies and discoveries have turned up


Summarize Sex Determination (in humans)
o Bio text - bottom of p 341-top of 342

What is linkage? What are linked genes?
o Bio text p 279-280

