About This Quiz & Worksheet

This quiz and helpful worksheet will check your understanding of a monohybrid cross and the genetic characteristics of the offspring of mammals and plants. You will be tested on such topics as body combinations, organism pairings, and the experimental details of the monohybrid cross creator, Gregor Mendel.

Quiz & Worksheet Goals

In this worksheet and quiz, you will be tested on:

  • What a monohybrid cross is
  • Gregor Mendel's pea plant hybrids
  • Relationship between genotypes and phenotypes in a monohybrid cross
  • Inheritance of disease via a dominant/recessive model
  • Ratio of offspring characteristics

Skills Practiced

  • Reading comprehension - ensure that you draw the most important information from the related science lesson
  • Problem solving - use acquired knowledge to solve monohybrid cross practice problems
  • Distinguishing differences - compare and contrast topics from the lesson, such as dominant and recessive

Additional Learning

For more information on this topic, review the lesson titled Monohybrid Cross: Definition & Example, which delves deeper into the following:

  • Gregor Mendel
  • Definition of 'hybrid'
