Discuss similarities and differences. Students will design a set of Potato Heads around a theme. During the second phase, students will complete a constructed response to explain and apply what they have learned about heredity and genetics.
Students will complete the formal lab report in which they must identify the parental and offspring genotypes and phenotypes, but also must explain the ratio and proportion of traits that pass from parents to offspring.
Heredity and Genetics The teacher will continue through the PowerPoint to review main concepts and discuss the different examples. How will the teacher assist students in organizing the knowledge gained in the lesson?
Why are some traits expressed and others not? Use images of siblings that show a strong resemblance, and then show an image of siblings that do not appear to be related. Next, students will view pictures of celebrity siblings the teacher will need to conduct a search of celebrity siblings and place the images on slide 3.
Students will be able to approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency.
Feedback to Students The teacher will provide verbal feedback during discussions and group work. Students should be able to demonstrate an understanding: For the next activity, assign students to pairs. Relate these images to the idea of what is heredity. Students need to come to this project with an understanding that: Do I have dominant or recessive traits?
Students will be able to compute unit rates associated with ratios and fractions, including ratios of lengths, areas, and other quantities measured in like or different units.
Students will take notes on the principles of genetics. For the next slide, find images of celebrity doppelgangers. Formative Assessment Students will be given many points throughout the project to demonstrate understanding from the first engage activity to the practice problems to the engineering challenge.
What prior knowledge should students have for this lesson? What should students know and be able to do as a result of this lesson? Introduce students to the STEM design project.
Provide struggling readers with a copy of the visual vocabulary cards see attached Genetics Visual Vocabulary Consider printing out a copy of the PowerPoint in notes format to provide extra support Group students heterogeneously when working on the project Extensions: Potato Head Genetics Quiz that will assess their ability to explain how traits are inherited and passed on to offspring see attached Mr.
Students should demonstrate an understanding that the chances of traits being expressed in offspring can be determined using Punnett squares. General Lesson Plan Learning Objectives: How will the teacher present the concept or skill to students? The teacher should have guiding questions available ahead of time to promote successful discussion see attached Genetics Ethics Guiding Questions PowerPoint.
There are factors that can impact expressed traits. How can you tell? They must use evidence to support their answers. The teacher will provide written feedback after the final assessment and practice sheets. How can we predict heredity and why is it important?This product is a 3 page practice problem worksheet on codominance and multiple alleles.
The problems cover blood types and coat color in rabbits. There are 13 problems. Some of the problems are monohybrid and some of the problems are dihybrid.
1 of 2 GENETICS PRACTICE 1: BASIC MENDELIAN GENETICS Solve these genetics problems. Be sure to complete the Punnett square to show how you derived your solution.
1. In humans the allele for albinism is recessive to the allele for normal skin pigmentation. In seals, the gene for the length of the whiskers has two alleles. The dominant allele (W). Genetics Practice Problems #2 - Writing Alleles.
Directions: Using the data in Table 1, write the genotype that corresponds to the phenotype descriptions. Practice with Crosses. Show all work! 5. A TT (tall) plant is crossed with a tt (short plant).
What percentage of the offspring will be tall? Genetics and Proportions Design Challenge Submit Feedback / Report Problems x. Show Remarks/Examples SCL Determine the probabilities for genotype and phenotype combinations using Punnett Students will explore principles of heredity through an activity where they design a themed Potato Head toy set.
Subject(s). Genetics: Practice Problems and Solutions gives students the opportunity to apply their knowledge of core genetics principles and concepts.
Designed to work well with any genetics text, it features more than short answer and conceptual problems. Multiple Alleles. 5. Epistasis. 6.
