Question

Genetics Problems Solve each of following genetics problems, showing all work. Assume complete dominance, unless otherwise stated. 1. In pea plants, flowers can be purple or white due to an autosomal gene. Purple is the dominant color, from the allele T. If two plants with genotypes TT and Tt, respectively, undergo meiosis to form pollen and eggs. What is the genotypic make up of the gametes for each parent? Note: Mendel's Law of Segregation states that "factors segregate during gamete formation". gamete(s) from TT plant: gamete(s) from Tt plant: 2a. Using the information in question #1, what is the phenotypic ratio of flower color from a cross between two white flowering plants? 2b. What is the phenotypic ratio from a cross between two heterozygous, purple flowering plants?
