In objective #5 we will be looking at pedigrees and the different patterns of inheritance a pedigree can show us. If you don't know what a pedigree is, see the example below:
There are four main possible patterns of inheritance we see in pedigrees. These four are listed below:
autosomal dominant
autosomal recessive
sex-linked dominant
sex-linked recessive
a) Based on your knowledge of autosomes and sex-linked traits, write down what you think EACH pattern of inheritance is in the answer to this journal. NO GOOGLING!
