    Punnett Square for Question #4 is a the top Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

    8) You plant some of Johnny and Jenny's offspring. Two in particular become your favorite plants and you name them Jamie and Josie. You decide to cross these two plants together (you can cross siblings in plants, but this is not really something that occurs very often in humans for various reasons!). Place the gametes that would result from meiosis in Jamie and Josie in the top row for Jamie and left column for Josie of the Punnett square. Then...
