The probability of two or more independent events occurring simultaneously is equal to the product of their individual probabilities. If you cross , what is the probability of getting an aabba a b b offspring? The probability of getting . The probability of getting Total probability = The Sum Rule (The "Or" Rule)
Both alleles are expressed simultaneously and distinctly in the heterozygote (e.g., AB blood type, or roan fur). Sex-Linked Inheritance
When two genes do not assort independently, they are linked on the same chromosome. Linked genes travel together during meiosis unless a crossover event separates them. Calculating Recombination Frequency The probability of getting Total probability = The
If you are compiling these materials into a downloadable PDF for study or teaching purposes, ensure your document includes these structural elements for optimal utility:
Males ( XY ) only need one copy of the allele to express the trait. Females ( XX ) must inherit two copies to express the trait.
Choose clear, unambiguous letters to represent alleles. Use uppercase letters for dominant alleles and lowercase letters for recessive alleles. For sex-linked traits, always write the alleles as superscripts on the sex chromosomes ( XBcap X to the cap B-th power Xbcap X to the b-th power Step 4: Reconstruct Parental Genotypes unambiguous letters to represent alleles.
