More Crosses with Pea Plants: The Principle of Independent Assortment In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all three loci is self-crossed, and 2,048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled peas?
Required information A heterozygous tall pea plant is allowed to self-fertillze. From the F1 progeny, a phenotyplcally tall plant was randomly chosen and mated to a phenotypically dwarf pea plant.

2. Show a dihybrid cross of a plant with a genotype of heterozygous green leaf and heterozygous smooth leaf blade and another plant with a genotype of homozygous green leaf and homozygous serrated leaf blade. Consider green (WW) is dominant over white (ww) while smooth (SS) is dominant over serrated (ss). What are the possible offspring from this cross? Give the phenotype, genotype and their ratio. Make sure the phenotype and genotype were aligned with its ratio.
