  • Genetic diagrams and monohybrid crosses

    We discuss the structure of genetic diagrams and use the diagrams to show inheritance in monohybrid crosses to determine the percentage chance of an offspring inheriting a specific characteristic from their parents.

  • Monohybrid crosses

    We investigate crosses between individuals when there is incomplete dominance between the different characteristics and what the phenotypes will look like in such cases. We do the same with co-dominant traits.

  • Genetic crosses: Inheritance of sex a...

    We take a look at how the sex of an individual is determined and we also investigate genetic crosses where multiple alleles exist for example blood types in humans
