Ch 14-15 Exam Next Class

Journals due next class, just a reminder I am only collecting journals that are labeled as "journal 1," "Journals 2, " etc. See prior posting for any journals you may have missed!

NEW JOURNAL…..NEW RULES!!!!!!!!!!
For FULL credit journals MUST be labeled by journal entry!

Journal 1 Chap 14/15
Read page 252 and provide some “facts” about who Mendel was!

Journal 2 Chap 14/15
1) Cross a homozygous dominant tall plant with a heterozygous tall plant and anaylyze the genotypical outcomes of the F1 generation…phenotypical….
2) Which of the following are genotypes and which are gametes?
a. AA
b. A
c. Bb
d. BB
e. C

Journal 3 Chap 14/15
1. BbDD (B brown, D deaf) is mated to one with BBdd. What is the chance of obtaining an offspring that is
a. Brown/NOT deaf?
b. Brown/deaf?
2. When you are done with this journal finish your ws from last class…we are going to have an overhead of notes in just a sec!

Journal 4 Chap 14/15
Do overhead practice problem set 11.5

Journal 5 Chapter 14/15
Considering incomplete dominance and the following key answer the following question.
TA = tall
TB = short
PR = purple
PQ = white

Parents = TATBPRPQ x TATAPRPR

1. What are the chances of having a medium/lilac flower?

Journal 6 Chapter 14/15
gene
allele
principle of segregation
principle of independent assortment

different forms of a gene for the same trait

The law that states the different forms of two alleles (homologous chromosomes) will separate independently of each other into different gametes

a segment/piece of DNA that codes for a trait

This law states that factors for different characters (on different chromosomes) separate independently of each other. This is why you have to consider EVERY possible combination that can occur when you are tracking a dihybrid cross

Journal 7 Chapter 14/15
1. Using pages 265-268 make a list of all the autosomal dominant and a list of the autosomal recessive inherited disorders and provide a brief explanation of each.
2. Note to self, please be sure to read and understand pages section 15.4 of your book. We may not be going over this in class but it will be on the test! Show PPT on this from notes!
3. Today Jenkins will show you some examples of sex chromos altered

Journal 8 Chapter 14/15

Make sure your journals are in order for next class when they will be checked off

Make sure to pay attention to chromosomal # abnormalities and autosomal dom/rec and sex linked diseases info..see blog for full description

1. Explain why generally, it is not possible to determine whether nondisjunction failed to occur in oogenesis or spermatogenesis. However, it is possible to assert that xyy resulted in nondisjunction in spermatogenesis

Decide whether the following statements apply to amniocentesis “A” or chorionic Villa Sampling “B”

2. Obtains cells from the region where the placenta will develop
3. Takes a sample from the amniotic fluid from the uterus
4. Can determine more types of abnormalities. In other words, is not limited to just a disorders revealed by a karyotype
5. Of the two procedures, this test has the lowest risk of a spontaneous abortion
6. This test can be done earlier in the pregnancy

7. Decide the inheritance pattern of the following pedigrees….be ready to explain!

Journal 9 ch 14-15
Mom: Dad
homozygous hemophilia Has hemophilia
homozygous cystic fibrosis carrier of cystic fibrosis
blood type AB Homozygous for blood B
Rh- Heterozygous Rh+
Heterozygous for Huntington’s Disease Heterozygous for Huntington’s


Showing your work mathematically, please give me the phenotypical fraction among all the offspring
that will be male hemophiliacs, with cystic fibrosis, blood type BB, Rh+, with Huntington’s
disease. Yes, I know this kid was dealt a bad hand of cards!
