Hi I was wondering if anyone had tips to remember
1. What chemicals/digestive enzymes are secreted by the liver, stomach, intestine (basically the alimentary canal)
2. Tips to deal with pedigrees
Hey anotherworld,
For 1 I know that the liver has catalase which can break down peroxides into oxygen, as for the stomach it contain sulfuric acid, I'm not quite sure about the intestines
For 2 you should remember a few things
1: Write down Generations (I, II, III, etc.)
2: Have a key (Square for Male, Circle for Female, patterns/coloured in shape for affected)
3: Analyse the relationship between the affected people and the pedigree (i.e. Does it skip a generation, does it only affect men, is it more apparent than the unaffected, can 2 non-affected parents produce and affected offspring etc)
4: Sometimes there will be a question with a paragraph and you have to construct the pedigree, read the question very carefully so you get the right relationships between people and who is affected.
5: Always use a ruler for the lines in a pedigree
6: It may help to write the Genotypes of each person in the pedigree to better grasp how the disease/disorder is passed down generations
Hope this helps
