2/19 & 2/20 Lesson 6 & 7

2/17/2014

6.Step 1
GQ..... On page 61 in your notebooks, under your vocab sheets, you need to find the definitions for the following words in the karyotyping paper we read and add them to your vocab: Karyotyping, Meiosis, Mitosis.

6. Step 2
On page 71 answer the following questions:
1. How many chromosomes does a human have?
2. How many homologous pairs does that make?
3. Which pair are responsible for the sex linked traits?
______________________________________________________________________________________________
6.Step 3
Finish your Karyotyping activity and turn it into the tray.
7. Step 4
Watch the Youtube Videos, sexual v/s asexual reproduction.
Grab the Mitosis v/s Meiosis packet and complete using the videos for help.
Complete the Mitosis packets and turn them in.
7. Step 5
Watch the Meiosis Videos and complete the Meiosis Packet.
Use the Interactive Mitosis v/s Meiosis link to compare both processes.

Learning Targets:
1. Analyze the human genome through karyotyping.
2. Compare asexual and sexual reproduction.

Intro: Asexual v/s Sexual Reproduction

GQ.... Create your own punnet square for your eye color, use your mother and fathers alleles. If you do not know your grandparents eyes, use a homozygous pair of alleles.

Agenda

Fruit Fly Genetics
Quiz
Karyotyping

Learning Targets
1. Investigate genetic technologies that we use today to create solutions to diseases.

2/13 & 2/14

2/12/2014

Directions....
1. Pick up a lab sheet at the front of the room. Sit with your group of 4 and fill in the data table by determining the genetic traits.
2. Get class totals.
3. Determine frequency by taking the number in the group/class totals. You should get a decimal. The highest frequency is the dominant trait for the class.
4. Get with a partner and create a punnet square for your offspring, complete with the genotype and phenotypes of at least 3 of these traits.

Agenda

Karyotyping activity

Learning Targets
1. Identify dominant and recessive traits by calculating their frequency.
2. create punnet squares to show genotype and phenotype of offspring.
