Understanding Dihybrid Crosses in Genetics

Learn what a genetic cross involving two traits, or dihybrid cross, reveals about inheritance patterns.

1,023 views

A genetic cross involving two traits is known as a dihybrid cross. It examines the inheritance patterns of two different traits simultaneously. For instance, crossing pea plants with green, round peas (GG/RR) with those having yellow, wrinkled peas (gg/rr) could produce offspring with various combinations of these traits, such as green and round (G/R), green and wrinkled (G/r), yellow and round (g/R), or yellow and wrinkled (g/r). This helps in understanding how different genes interact and assort independently.

FAQs & Answers

  1. What is a dihybrid cross? A dihybrid cross is a genetic cross examining the inheritance of two different traits simultaneously.
  2. How does a dihybrid cross differ from a monohybrid cross? A dihybrid cross involves two traits, while a monohybrid cross analyzes only one trait.
  3. What is an example of a dihybrid cross? An example involves crossing pea plants with green round seeds and yellow wrinkled seeds to observe trait combinations in offspring.
