Investigate how traits are inherited in corn plants by examining different ear types. Learn about dominant and recessive traits through hands-on experience!
If two corn plants with different traits are crossed, then the offspring will display a mix of those traits according to Mendelian inheritance patterns.

Observe and record traits of new corn ears.
Create a data chart of traits observed.
Analyze the inheritance patterns based on Mendelian genetics.
Draw conclusions based on your findings.
The data should reveal predictable inheritance patterns consistent with Mendelian genetics, showing ratios of dominant and recessive traits in the offspring.
