Homework due Thursday
Complete Blood Type Lab
Complete pedigree problem:

1. Heather has "short fingers" (brachydactyly).  She has two older brothers who are identical twins; both have short fingers.  Heather's two younger sisters have normal fingers.  Heather's mother has normal fingers, and her father has short fingers.  Heather's paternal grandmother has short fingers; her paternal grandfather, who is now deceased, had normal fingers.  Both of Heather's maternal grandparents have normal fingers.  Heather marries Tom, who has normal fingers; they adopt a son named Jeffrey who has normal fingers.  Jeffrey's biological parents both have normal fingers.  After adopting Jeffrey, Heather and Tom produce two children:  an older daughter with short fingers and a younger son with normal fingers. (Phew – that's a lot of family and fingers)
1. Using standard symbols and labels, draw a pedigree illustrating the inheritance of short fingers in Heather's family.
2. What is the most likely mode of inheritance for short fingers in this family?
3. If Heather and Tom had another biological child, what is the probability (based on your answer in b) that this child will have short fingers?

Non Mendelian Genetics

Welcome Back from Spring Break!!!!

  b) What is/are the genotype(s) of the silver offspring?
  c) What would be the phenotypic ratios of offspring produced by two silver blahblah birds?
  

• Codominance:

  A cross between a black cat & a tan cat produces a tabby pattern (black & tan fur together).
  a) What pattern of inheritence does this illustrate?
  b) What percent of kittens would have tan fur if a tabby cat is crossed with a black cat?

• Multiple Alleles: href="file:///C:%5CDOCUME%7E1%5CMISSVI%7E1%5CLOCALS%7E1%5CTemp%5Cmsohtml1%5C02%5Cclip_filelist.xml">

Cellular Respiration

Eeeek! What have we been doing in Biology?

Over the past week and a half we have been discussing cellular respiration:

• C6H12O6 + 6O2 -----> 6H2O + 6CO2 + ATP
