Document Summary
It is due at the end of lab during the week of november 5 (nov 7-9). For problems #1-3 the following information applies to the possible alleles. Stature: tall plant (t) is dominant over dwarf (t) Seed texture: round seed (r) is dominant over wrinkled seed (r) Flower color: yellow flowers (y) are dominant over white flowers (y) Problem #1: monohybrid cross: a homozygous tall plant (genotype_________) is pollinated by a, homozygous dwarf plant (genotype__________). Note: the plant that does the pollinating is called the pollen parent. It produces pollen that contains within it the sperm cell (male gamete). The plant that is pollinated is the female parent. A yellow flowered plant is pollinated by a white flowered plant. Indicate this by providing the genotype of each f1 used in the cross: f1 genotypes: ___________: give the genotypes __ __ __ __ __ __ __ __ x __ __ __ __ __ __ __ __ of the gametes.
