Understanding Monohybrid Crosses: The Basics of Genetic Combinations

Learn about monohybrid crosses, a key concept in genetics involving the inheritance of a single trait.

90 views

A genetic cross involving one trait is known as a monohybrid cross. It examines the inheritance of a single characteristic, where organisms are bred to determine the genetic basis of that trait.

FAQs & Answers

  1. What is a monohybrid cross? A monohybrid cross is a genetic cross that involves one trait, allowing researchers to study the inheritance of a single characteristic.
  2. How does a monohybrid cross help in genetics? It helps in determining the genetic basis of a trait by examining the inheritance patterns between different generations.
  3. What is an example of a trait studied in a monohybrid cross? An example of a trait studied in a monohybrid cross could be flower color in pea plants, where the inheritance of purple versus white flowers is observed.
  4. What are the expected ratios in a monohybrid cross? In a typical monohybrid cross, the expected phenotypic ratio in the offspring is usually 3:1, dominant to recessive traits.
