The "Technofied" Lesson Plan

Lesson goals

Students will understand the significance that pedigree charts have on family genetics.

Students will learn the anatomy of a pedigree chart by interacting with the smartboard to pair up symbols with terms

Students will gain the ability to create a pedigree chart based on a family background by identifying where specific family members go on the chart using the smartboard

Students will then learn how traits are linked to genetics by pairing up dominant and recessive genes with the appropriate trait/family member

Pedigree Chart Activity Pedigree Charts All living things have pedigrees. A pedigree is a diagram that shows the occurrence and appearance (phenotype) of a particular genetic trait, as it is passed from one generation to the next in a given family. From this information, along with an understanding of inheritance, genotypes of individuals can often be determined. Symbols for a Pedigree Chart Using the Smartboard application in our classroom, the teacher will introduce the different symbols in the pedigree chart.      The story below will be read as a class. After, we will create a pedigree together by having students volunteer and fill out the pedigree on the Smartboard. This is the story of Grandma and Grandpa Flipnob, and their clan! They were married way back in 1933 and have been just like newlyweds ever since. From their union, 4 individuals were created. Elizabeth, the eldest, was born in 1935. Fred soon followed in 1936. In 1939 Michelle was brought into this world. Mickey, a surprise to the whole family was the baby of the family, not being born until 1950. Elizabeth fell in love at a young age, and wed her high school sweetheart, David, in 1954. From this marriage, two bundles of joy came about (at the same time): John and Sonny – 1955 (twins!) It took Fred a little longer to find his soul mate. Finally in 1970, Fred found the woman of his dreams, Wilma, and they were married. Since they married so late in life, they only brought one new person into this world: Barney – 1972 Michelle was a hard working woman, and never found time in her schedule for love. She led a very productive and fulfilling life, but she never did marry and have children. Mickey was a wild one! After a long string of girlfriends, he finally chose Monica to spend the rest of his life with. They were wed in 1975 and brought two girls into this world: Krista – 1977 Janet – 1979 Answer the following questions: 1.     Who are the in-laws? 2.     What is the relationship between the people in the third generation? Now that you have your pedigree chart together, volunteers will shade in appropriate circles and squares on the Smartboard using the information below. Remember that individuals who possess the RECESSIVE trait are to be filled in completely. Individuals not shaded in carry at least one dominant allele. Dominant/Recessive Inheritance – Freckles Not having freckles is a recessive trait. Grandpa Flipnob did not have freckles, but his beautiful bride did. Fred and Michelle were the only two of their siblings to have freckles. Of the grandchildren, the twins did not have freckles, and neither did Barney, but the two girls did. Using the guide provided, we will match each family member with their specific gentotype by using the Smartboard. Remember, having no freckles is a RECESSIVE trait. STEP 1 Assign two recessive genes to any person on the pedigree whose symbol is shaded. Small letters are written below the person’s symbol. STEP 2 Assign one dominant gene to any person on the pedigree whose symbol is unshaded. A capital letter is written below the person’s symbol. STEP 3 Use the information given to you to determine the second alleles for each person with the dominant phenotype. We will check answers using the pedigree on the Smartboard. Example: We know that Grandpa Flipnob does not have freckles. If Grandma were BB, could any bb children be produced from Grandma and Grandpa? If Grandma were Bb, could any bb children be produced from them? Complete punnett squares below to determine your answer. 1.     From your results, what is Grandma’s genotype? 2.     What must be the genotypes of their children? 3.     What are the genotypes of their grandchildren? 4.     As a class, we will then label the pedigree on the Smartboard with the correct genotypes for each generation.
