Activity 66: Patterns of Pedigrees

Today students analyzed pedigrees of genetic traits. They noticed that dominant diseases show up in every generation and recessive diseases skip generations. Students made predictions about different pedigrees and labeled each person with two alleles. They then calculate the probability of the offspring getting the genetic disease.

Homework Due today: Critter Drawing and Description

Unit D Quiz 2

Today students completed unit D quiz two. The questions came from the last two weeks of instruction over Genetics. Students need to understand the difference between sexual and asexual reproduction, how tail color/dominance is determined, what budding is, and how the process of cloning works. Next students created their critter with the characteristics they determined from last class period. They will name the critter, describe its characteristics, and finally describe and draw the critters habitat.

Due today: Sponge Bob Genetics

Homework: Critter Drawing Due next block day either Wednesday or Tuesday

Activity #64-65: Breeding Critters

During block days this week students completed a couple different activities. First students read about the importance of chromosomes. They found out that every human cell except egg and sperm has a total of 46 chromosomes (23pairs). The sperm and egg only have 23 so when they combine for fertilization the offspring will have 46. Students also learned how genes are on chromosomes which determine traits. The last part of the reading was about mutations and how they can change chromosomes and genes. Next, students made critters with different traits ranging from nose size, body color, number of eyes and more. They created a creature with traits that were determined by tossing coins. Students will draw and describe their creature on Friday.

Homework: Sponge Bob Genetics due on Friday

Hint: Quiz on Friday

Genetic Disorder Presentations

Today students are presenting their projects on their specific genetic disorder. Students could create a power point, brochure, children's book, essay, public service announcement, and website. As students presented, the rest of the class took Cornell Notes on information that they gained from the presentations. Students were also able to listen to guest speakers from Regis University who are Nurses that work with babies on genetic disorders or diseases.

Homework Due Friday: Sponge Bob Genetic Worksheet

Activity # 61 : Gene Squares

During block days this week, students will be practicing using punnett squares to calculate the ratio of dominant to recessive traits. Students will be analyzing different traits to different the pattern of inheritance by observing the completed punnett square.

Homework: Genetic Disorder Project is Due on Friday

Activity #60: Mendel Reading

Today students finished calculating the ratio of tail color inheritance in critters. They should have found a 3:1 ratio of Blue to Orange tails. Blue is the dominant tail color and orange is the recessive tail color. Next students read about Gregor Mendel's genetic discoveries. As students read, they completed the SQP2Rs Strategy and took Cornell Notes about the reading. Students finished the class about writing a summary about Mendel's Genetics.

Due Friday: Genetic Disorder Project

Honors Class: Bring back signed contract

Activity 58-59 Gene Combo

Today students are tossing coins to determine the tail color of critters. If heads turns up then the tail color is blue T and if tails turns up then the tail color is orange t. Students will calculate the ratio of tail color and determine which trait is dominant and which trait is recessive.

Hint: TT =Blue Tt=Blue tt=orange
