# CTE Resource Center - Verso - Forensic Technology Task 17023795

# Calculate blood type probabilities, using Punnett squares.

## Definition

Calculations should be based on a monohybrid cross, using genes for blood types to create the probabilities of blood type in offspring.

## Process/Skill Questions

• To what extent do parents dictate their child’s blood type?
• What role does blood typing play in forensic science?
• In what ways can one determine his/her probable blood type?

## Mathematics

### AFDA.6

The student will calculate probabilities. Key concepts include
1. conditional probability;
2. dependent and independent events;
3. mutually exclusive events;
4. counting techniques (permutations and combinations); and
5. Law of Large Numbers.

### PS.3*

The student will compare distributions of two or more univariate data sets, numerically and graphically, analyzing center and spread (within group and between group variations), clusters and gaps, shapes, outliers, or other unusual features.

### PS.11*

The student will identify and describe two or more events as complementary, dependent, independent, and/or mutually exclusive.

### PS.12*

The student will determine probabilities (relative frequency and theoretical), including conditional probabilities for events that are either dependent or independent, by applying the Law of Large Numbers concept, the addition rule, and the multiplication rule.

### PS.14

The student will simulate probability distributions, including binomial and geometric.

## Science

### BIO.4

The student will investigate and understand life functions of Archaea, Bacteria, and Eukarya. Key concepts include
1. comparison of their metabolic activities;
2. maintenance of homeostasis;
3. how the structures and functions vary among and within the Eukarya kingdoms of protists, fungi, plants, and animals, including humans;
4. human health issues, human anatomy, and body systems;
5. how viruses compare with organisms; and
6. evidence supporting the germ theory of infectious disease.
