Corn Segregating Ear, R Color Alleles 3:1

Product Code: 176500

Description

 

What’s the fastest way to explain the relationship between genotypes and phenotypes? Use this one ear of corn! Carolina’s Corn Segregating Ear, R Color Alleles 3:1 is an educational resource designed for studying Mendelian genetics and inheritance patterns. It features an ear of corn with kernels that visually demonstrate a 3:1 phenotypic ratio for kernel color, following classic Mendelian segregation principles.

Key Features:

  • Genetics Focus: This corn variety carries the R (red) and r (colorless) alleles, demonstrating dominant and recessive inheritance.
  • Phenotypic Ratio: The kernels display approximately 75% red and 25% colorless, illustrating the expected results of a monohybrid cross (Rr × Rr).
  • Hands-On Learning: Students can count and categorize kernels to calculate observed vs. expected ratios and apply chi-square analysis to test for statistical significance.
  • Real-World Application: Helps students understand how traits are passed from one generation to the next and reinforces key genetics concepts like dominance, probability, and independent assortment.
