Transcript with Timestamp
0:00 Introduction — Interpreting given pedigrees (not plotting)
1:03 2 Golden Rules for interpreting any pedigree
1:15 Rule 1: Trait in ALL generations → likely DOMINANT
2:00 Rule 2: If father is affected and son is also affected → CANNOT be X-linked
3:37 Pedigree 1 conclusion: Autosomal Recessive
3:55 Cross-check using Thalassaemia (autosomal recessive) example
5:04 Genotype analysis of all individuals in Pedigree 1
7:10 Pedigree 1 confirms: autosomal recessive inheritance
8:05 Pedigree 2 — parents unaffected, 2 sons affected, daughter and son unaffected
8:28 daughter marries normal man → son and daughter also affected
8:46 Pedigree 2 Rule 1: not in all generations → NOT dominant
8:55 Pedigree 2 Rule 2: males AND females affected → NOT sex-linked
9:15 4 disease options: Haemophilia, Colour Blindness, PKU, Hypertrichosis
9:56 Only recessive autosomal disease in the list = Phenylketonuria (PKU)
10:36 Summary — 3 clues for pedigree interpretation
