Proficiency Assessment
H.1L.3 Heredity
Standard: Explain and apply laws of heredity and their relationship to the structure and function of
DNA.
Title: You Must Choose, But Choose Wisely
Introduction
Mendelian Genetics
 Dominant/recessive inheritance
 X-linked inheritance
 Codominant/Incomplete dominance
 Polygenic inheritance
 Punnett Squares (monohybrid)
 Homozygous/Heterozygous
 DNA and Heredity
 DNA makes up a chromosome
 Chromosomes are organized into segments called genes
 Genes code for proteins
 Proteins produce traits of an organism
 Genotype/Phenotype
Vocabulary: homozygous, heterozygous, phenotype, genotype, pedigree, Punnett Square, carrier,
color-blindness, crossover, genetic expression, generation (P1, F1, F2), hemophilia, karyotype, mutation,
non-disjunction, polygenic, sequence, sex-linked, endomorph, ectomorph, mesomorph
Possible learning targets:
Explain the laws of heredity.
Explain the relationship of the laws of heredity to the structure of DNA.
Explain the relationship of the laws of heredity to the function of DNA.
Apply laws of heredity.
Assessment
In the role of a genetic counselor at a sperm bank, students must identify genetic traits, including
phenotype and genotype, for individuals in the bank and evaluate the “best” match for a fictitious
couple, Bella and Edward. They must know basic laws of heredity and what causes some deviations
from those laws. It is essential that students have some exposure to human genetic traits and likely
should have experienced the process of genetically constructing a child following simplified rules.
Type: Case Study/Essay
Time needed: 1-2 class periods
Materials: Paper and pencil – can be typed at teacher’s discretion, copies of Face Trait Key and
donor tables

Directions: Deliver student task description, donor files, trait key, and scoring guide to
students. Give them time to process and write.

You Must Choose, But Choose Wisely
You are a genetic counselor at the local fertility clinic, The Michael Phelps Memorial Sperm Bank. A
young couple, Bella and Edward, has been referred to you after discovering that Edward has an
extraordinarily low sperm count and cannot successfully impregnate Bella. In your database, you have
hundreds of sperm donors’ characteristics listed. You must select the appropriate donor for Edward
and Bella.

Use your body traits key to establish possible genotypes for each trait, then prepare a report for
Edward and Bella detailing what traits you would recommend looking for in a sperm donor. Explain
why you would recommend those traits. Explain why the selection of a sperm donor may not result in
the desired traits appearing in their child and what might cause unexpected traits to appear.
