Genetics Project: Design a Species
For this project, you are going to create an imaginary Creature displaying 6 different traits. There are two parts
to this project – in Part I you will draw your creature illustrating the 6 different traits, and in Part II you will apply
the traits of your creature and complete the required practice problems. The creature that you create can be
living or non-living, as long as your creature fulfills the following criteria….
Part I
Your creature must have at least 6 different genetic traits. For the six traits required, you must show:
 3 single allele traits (simple traits showing dominant/recessive pattern)
 1 co-dominant trait
 1 incomplete dominant trait
 1 multiple allele trait (trait where there are more than 2 alleles)
Remember blood type in humans? The IA allele and IB allele are co-dominant over the i allele, which is
recessive. Genotypes IAIA or IAi show the Type A phenotype, whereas genotypes IBIB or IBi show the
Type B phenotype. Genotype IAIB shows BOTH (hence, the co-dominance) the A and B phenotype.
Genotype ii shows a Type O phenotype (completely different than A or B).
1. For EACH trait, you must describe, sketch, and color examples of your creature. The examples must
have different phenotypes. For each trait, include a title (descriptive of the pattern of inheritance), a key,
as well as all possible genotypes and phenotypes for that trait. For example, let’s say that your creature
was an alien, and one of your single allele traits was height. Here is an example of what your page would
look like:
Single Allele Trait: Height
Key: T = 3 inches tall
t = 1 inch tall
Genotype: TT or Tt
Phenotype: 3 inches tall
Genotype: tt
Phenotype: 1 inch tall
2. Use only white, unlined paper for this project. You can use one sheet of paper for up to 4 traits – you
can put two traits on the front, two on the back – just make sure you neatly divide your paper in half so
that the different traits are easily visible.
Part II
For Part II, use a separate sheet of paper (notebook paper is fine) and complete the following problems.
1. Use two of your creature’s single allele traits and show a dihybrid cross (EX: Height and Color TtBb x
ttBb). Show the Key, Cross, how you formed the gametes, the Punnett Square, and both the
genotypic and phenotypic ratios produced.
2. Using any of your creatures traits from Part I, create 5 practice problems. The problems need to be
written in complete sentences, in word problem format. You do not have to actually solve these problems,
but they must be solvable.
