Design a Species (pgs 41-43)

Genetics Project - Design a Species (from biologycorner.com)

Due March 7, 2014

Objective: Genetics follows certain rules, as illustrated by Punnett squares, principles of dominance and recessiveness, and rules related to the location of alleles on the chromosomes. In animals, such as mouse, certain traits are expressed in predictable ways. In this project, you are going to design your own imaginary species, and create traits for the species that follow genetic rules that you have already studied.

The creature should have at least 5 genetic traits from the following list. You are free to create whatever traits you like (such as hair color, size, shape, or other features)

• 2 Single-allele traits
• 1 Codominant trait (or incomplete dominance)
• 1 Multiple allele trait
• 1 Sex linked trait

Your final project should have the following elements:

1. Describe or sketch each of the traits from the list, listing genotypes and phenotypes for each. Partial sketches are fine in this case.

2. Sketch two examples of your creature – one male and one female. The two examples must have different genotypes. Each sketch should have the genotype listed for all traits.

3. Pick one of your single allele traits and create a sample pedigree for your creature. The pedigree should include at least 4 generations.

4. Show a dihybrid cross (using your 2 single allele traits—ex: AaBb x AaBb) List the phenotypic ratios.

5. Create 5 practice problems, using any of the traits. These should be word problems. Do not just write Aa x Aa.

Genetics Project Grading Rubric
	Unsatisfactory (3 pts)	Satisfactory (4pts)	Excellent (5 pts)
Traits and pictures	Some do not follow genetics “rules”, pictures not clear	Follows genetics rules, pictures are small or lacking in creativity or effort	Follows genetics rules, pictures are drawn large and clearly. Colored. Creative.
Creature examples	Genotype doesn’t follow phenotype, pictures not included or unclear	Genotype follows phenotype, all traits included, pictures drawn clearly, neatly, creatively and colored	Genotype follows phenotype, pictures drawn clearly, neatly and creatively, and colored, model of both sexes made (with a key) and shows all traits
Pedigree	Less than 4 generations are shown, significant mistakes in genotypes	4 generations shown, minor mistakes in genotypes	4 generations shown, no mistakes
Dihybrid Cross	Punnett square not set up correctly, phenotypic ratios not given or incorrect	Punnett square set up correctly, minor errors in counting and ratios	Square set up correctly, phenotypic ratios given correctly
Practice problems	Less than 5 problems given, more than 1 is impossible to solve	5 problems given, somewhat unclear or unsolvable	All 5 problems are written well and can be solved

Tuesday 2/18 Work on Notebooks

You should have received quite a few things from the sub to put into your notebook.
Please work on all pages so that you have everything done up through pg 40 (notes on Bird video)
Here is what you should have on the last few pgs . . . 

• 35 Blood Lab results
• 36-37 Sex Linkage
• 38-39 Pedigree Analysis

pgs 31-34 more genetics stuff

pg 31 More examples of Incomplete and Co-dominance 

pg 32-33 Multiple Alleles in Blood Groups 

pg 34 Lethal Alleles

Investigating Inherited Traits lab (pgs 29-20)

Follow the procedures below, and use the traits table (also below) to determine what your offspring will look like.  Data goes on pg 29, drawing of offspring on pg 30
