Molecular Basis of Cancer (Oncogenesis)
Q: All cancers start with a single somatic mutation that changes other cells. True or False?
Did You Know?
This is a classic Mendelian inheritance problem. Both parents have genotype A/O. Each parent can pass on either an A allele or an O allele with equal probability (50% chance each). To have a child with blood type O (phenotype O, genotype O/O), the child must inherit an O allele from the father AND an O allele from the mother. The probability of inheriting an O allele from the father is 1/2. The probability of inheriting an O allele from the mother is also 1/2. To find the combined probability of both independent events happening, we multiply: (1/2) * (1/2) = 1/4. Therefore, there is a 25% chance (or 1 in 4 probability) that this couple will have a child with blood type O.
