Genetic diagrams and monohybrid crosses


Up Next in Term 2

  • 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

  • Dihybrid crosses and pedigree diagrams

    We discuss dihybrid crosses where two independent alleles are investigated to determine the chances of two different characteristics occurring in the same individual. We also look at pedigree diagrams and how inheritance can be determined by using these diagrams.
