RHS Weekly Lesson Plan Template: Bennett Jacobs –Animal Science Technology Time Dates 10.27 Monday 10.28 Tuesday 10.29 Wednesday 10.30 Thursday 10.31 Friday Standard Explain the basic function of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Explain how traits are passed from parent to offspring through genetic transfer. Research the concept of dominant genes verses recessive genes. Describe the concept of co-dominant genes. Explain how producers use the laws of genetics to produce the type of livestock they want. Explain how the sex of an animal is determined. Research the concept of dominant genes verses recessive genes. Describe the concept of co-dominant genes. Explain how producers use the laws of genetics to produce the type of livestock they want. Explain how the sex of an animal is determined. Explain the difference between phenotypic and genotypic characteristics. Compute mathematically the expected color of offspring. Compare the expected coat color with results obtained through scientific observation. Describe how the concept of heritability is used in the selection of livestock. Predict phenotypic and genotypic characteristics in animals. Utilize performance data in the selection of livestock. Describe Expected Progeny Difference (EPD). Essential Question/ Key Question What is DNA and RNA and how are traits passed from parent to offspring? Why are genes important? Why are genes important? What is the Punnett Square and how can it be of use? What are EPDs and how can they be of use? Lesson Opener Ask students about the importance of DNA technology in the legal system. What do students already know about natural selection? Are certain genes better? Does it depend? Have students list what traits they believe they inherited from each parent. Why do people use player and team statistics to wage bets? Procedures/Strategies Introduce students to new vocabulary. Discuss the relevance of genetics to the animal and livestock industry through use of a Powerpoint. Discuss dominant vs recessive and co-dominant genes. Discuss how the sex of an animal is determined. Discuss the how the sex of an animal is determined. Discuss how and why livestock producers use genetic information to better their herd. How can they obtain that information, what does it look like? Demonstrate to class how to use the Punnett Square. Discuss its usefulness and work through some examples in small groups. Discuss heritability and the use of EPDs in today’s livestock herds. Why do these EPDs give us? How do we use them and are they really that valuable? Show class example EPDs of several different bulls and explain when each might be of benefit. Lesson Summary Recap vocab terms and reiterate how genetics can be economically beneficial in the livestock industry. Overview of dominant, recessive and co-dominant genes. Recap how sex of an animal is determined and why producers use genetic info to better their herd. Summary of key points when using Punnett Square. Review what an EPD is, how it’s used and what the most widely used of the EPDs include. Assessment/ Evaluation Put students into groups and have them come up with pictures that describe the vocab term assigned to their Socrative submission. Teacher assessment during discussion. Assign students a basic Punnett Square to complete Give students essential EPD information for 4 cows and based on the needs of the herd ask them which cow 5-10 min.
