Punnett Squares

Punnett Squares

This webinar on Punnett squares covers one of the main ways of understanding classical genetics. You will learn about Mendel’s laws, as well as the differences between genes, alleles, and loci. You will also review how to set up Punnett squares for monohybrid and dihybrid crosses, and how to calculate probabilities from Punnett squares.

At a glance


Essential skills

  • Calculate simple and conditional probabilities from Punnett squares

  • Be able to set up Punnett squares for monohybrid and dihybrid crosses


Knowledge Fundamentals

  • The differences between genes, alleles, and loci

  • Mendel's laws

  • Monohybrid vs dihybrid crosses, autosomal vs sex-linked inheritance patterns, and linked vs unlinked genes


On the MCAT

  • Punnet squares are not hard, but this test will take an easy topic and make it unfamiliar/hard by the wording of the question

  • Calculating probabilities often require fractions; please make sure you are well-practiced in this area, however elementary it may seem


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
