A pedigree is a genetic representation of a family tree that diagrams the inheritance of a trait or disease though several generations. The pedigree shows the relationships between family members and indicates which individuals express or silently carry the trait in question. The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905. The diagram is used by biologists to determine the probability of an offspring having a particular genotype. Problem: A person who is albino lacks pigment in the skin. This trait is due to a recessive alle. An albino man marries a woman who is normally pigmented. One of the woman's parents was albino. What is the possibility that their first child will be albino? #Genetics #geneticDisorder #geneticDisease #PunnetSquare #pedigree #PedigreeAnalysis #pedigreeAnalysisPractice #pedigreeAnalysisGenetics #pedigreeAnalysisProbability #pedigreeAnalysisAnswers #pedigreeCharts #HowToSolvePedigreeProblems #solvePedigreeProblems #solvingPedigreeProblems #pedigreeProblemsAndSolutions #howToAnalyzePedigree #analyzingPedigree #geneticsProblems
