Patterns of Inheritance/Organism Design 
Students design an imaginary organism to show patterns of inheritance in several chosen traits. The traits must include examples of complete dominance, incomplete dominance, codominance, multiple alleles for a trait, and epistasis. Students will demonstrate understanding through visual description of phenotypes, explanation of inheritance, and description of a habitat/environment where the organism is well-adapted for living.

Inheritable Traits

Minimal

Less than 7 traits described

Many or all traits from list of examples

Missing more than one of the required patterns of inheritance
Basic

8-9 Traits described

May include more than 7 from the list of examples

Missing one of the required patterns of inheritance
Proficient

10 Traits described

No more than 7 from the list of examples

At least one each of:
complete dominance, incomplete dominance, codominance, multiple alleles, and epistasis
Advanced

More than 10 traits described

Many traits not from the example list

Multiple examples of inheritance other than complete dominance

May include some traits showing more than one pattern of inheritance
Evidence of Crosses

Minimal

Punnett square showing a cross between heterozygous parents given for less than 8 traits with 2 alleles, those with multiple alleles show all possible alleles in the cross

Few crosses accurate
Basic

Punnett square showing a cross between heterozygous parents given for 8-9 traits with 2 alleles, those with multiple alleles show all possible alleles in the cross

Most crosses accurate
Proficient

Punnett square showing a cross between heterozygous parents given for each trait with 2 alleles, those with multiple alleles show all possible alleles in the cross

All crosses accurate
Advanced

Punnett square showing a cross between heterozygous parents given for each trait with 2 alleles, those with multiple alleles show all possible alleles in the cross

All crosses accurate

Includes a discussion of expected outcomes and ratios of results
Visual Diagram/Drawing

Minimal

Some phenotypes of traits represented, may be missing all for a given trait

Visual of complete organism shows some traits and likely does not match results of coin toss
Basic

Most phenotypes of traits represented, with at least one phenotype per trait

Visual of complete organism shows most traits and may not directly correspond to results of coin toss
Proficient

All phenotypes of all traits represented

Visual of complete organism included after traits determined by coin flip (roll of die for multiple alleles)
Advanced

All phenotypes of all traits represented

Visual of complete organism included after traits determined by coin flip (roll of die for multiple alleles)

Clearly shows alignment with corresponding genotypes
Traits

Minimal

Several traits not addressed

Lack of connection between structure and function
Basic

Structure of traits described, but not all functions

Description is typed
Proficient

Structure of traits described

Function of traits described in context of structure (connection made between the two)

Description is typed
Advanced

Structure of traits described

Function of traits described in context of structure (connection made between the two)

Description is typed

Discussion included relating how traits working together may have certain function
Environment

Minimal

Environment description incomplete, leaving out some characteristics and little connection made to organism
Basic

Description of environment includes general characteristics of the habitat (ground cover, water availability, plant life) with some connections made to organism

Description is typed
Proficient

Description of environment includes general characteristics of the habitat (ground cover, water availability, plant life)

Specifically addresses organism's shelter, food source, and possible predators

Description is typed
Advanced

Description of environment includes general characteristics of the habitat (ground cover, water availability, plant life)

Specifically addresses organism's shelter, food source, and possible predators

Discusses phenotypes within the population that would allow for adaptation due to changes in the environment

Description is typed
