Understanding Monohybrid Crosses in Genetics

Learn about monohybrid crosses and how they explain inheritance of single traits in genetics.

490 views

A genetic cross between two individuals involving one character is known as a monohybrid cross. This type of cross examines the inheritance of a single trait or gene. For instance, crossing two pea plants that differ in a single trait, like plant height (tall vs. short), helps determine how this trait is inherited in offspring. Monohybrid crosses are essential in understanding basic principles of genetics, such as dominant and recessive alleles.

FAQs & Answers

  1. What is the purpose of a monohybrid cross? A monohybrid cross determines how a single trait is inherited from two parent organisms.
  2. How do dominant and recessive alleles affect inheritance? Dominant alleles will mask the effect of recessive alleles, influencing the traits expressed in offspring.
  3. What are some examples of traits examined in monohybrid crosses? Common traits include characteristics like plant height, flower color, or seed shape in plants.
