About This Quiz & Worksheet

In this quiz, it is assumed you've already learned the theory of Mendel's First Law. Here, you will be applying it to examples.

Quiz & Worksheet Goals

This quiz is about the application of Mendel's First Law and will test how well you understand:

  • Genotypic ratios
  • Dominant phenotypes in monohybrid crosses
  • Interpreting genotypes of animals given specific traits

Skills Practiced

  • Reading comprehension - draw the most important information from the lesson on applying Mendel's First Law
  • Critical thinking - use this information to consider what could be true about an animal's genetics
  • Problem solving - figure out percentages of dominant phenotypes

Additional Learning

There can be a lot to process about this topic. So, we recommend you read or re-read the lesson on the Application of Mendel's First Law, which covers the following objectives:

  • Define the law of segregation
  • Know how generations in genetic crosses were named
  • Define Punnett square
  • Define monohybrid cross
  • Understand how to predict the outcome of a monohybrid cross
  • Interpret the results of a Punnett square
