### BIO 340 Activity #3: Hybrid Crosses, Probability & Pedigrees**Name (Last, First):** _____________________---#### I. Genetics of Drosophila MelanogasterIn the fruit fly *Drosophila melanogaster*, tan body color (B) is dominant to black (b), and dark red eyes (E) is dominant to bright orange (e). A black fly, heterozygous for eye color (Fly #1) is crossed to an orange-eyed fly, heterozygous for body color (Fly #2).1. **Genotypes of the parents?** - Fly #1: _______________ - Fly #2: _______________2. **Gametes from each parent?** - Fly #1: _______________ - Fly #2: _______________3. **Ratios of gametes from each parent?** - Fly #1: _______________ - Fly #2: _______________**Complete the following Punnett square.** Indicate gamete genotypes from each parent and all offspring genotypes.- What proportion of offspring are: - Tan & dark red: __________ - Tan & orange: __________ - Black & dark red: __________ - Black & orange: __________Diagram: A blank 4x4 Punnett square is shown, labeled for Fly #1 and Fly #2 gametes.---#### II. Probability CalculationsWhat is the probability that this pair of parents will produce the indicated offspring?- **Genotypes: Aa Bb DD x aa Bb Dd ➔ Aa Bb Dd****Punnett squares for each trait can help with this calculation!**- Probability (P) of Aa Bb Dd = P (Aa) ____ x P (Bb) ____ x P (Dd) ____ = ____Diagram: Three blank Punnett squares corresponding to each genetic trait.---#### III. Analysis of PedigreesFor each of these three pedigrees, determine the likely mode of inheritance and the probability that the individual marked with a diamond (◇) will express the trait.**A. Pedigree with Generations I-IV**1. **Mode of Inheritance:** _____________________2. **Probability that ◇ expresses the trait:** ______**B. Pedigree with Generations I-IV**(C1) Mode of Inheritance: __________________
