Onion Genetics Part 1. We will begin by looking at onion color. Let's arbitrarily assign the letter "R" for color and say red onions are dominant (R) and white onions are recessive (r). Cross an individual who is heterozygous with an individual who is homozygous recessive. 1. What is the genotype of the heterozygous individual? 2. What is the genotype of the homozygous recessive individual? Complete the Punnett square using the alleles you just listed. 3. What are the resulting genotypes and their ratios or %? 4. What are the resulting phenotypes and their ratios or %?
