Part 2. Do one more example of a monohybrid cross. This time assign the letter "B" for onion taste. Being sweet is dominant controlled by allele (B) and being bitter is recessive-controlled by allele (b). Cross individuals who are both heterozygous for this trait. 5. What is the genotype of each of these heterozygous individuals? 6. What is the phenotype of these heterozygous individuals? Complete the Punnett square below using the alleles you just listed. 7. What are the resulting genotypes and their ratios or %? 8. What are the resulting phenotypes and their ratios or %? Figure 3. Monohybrid Cross for Onion Taste. 103

F₁ generation 1. Parents with the following homozygous genotypes for both traits were crossed in order to produce F₂ offspring. RRSS x rrss (Purple, Smooth) x (yellow, wrinkled) What types of gametes can each parent produce? RRSS rrss (Remember how we determine gamete combinations of genes located in non-homologous chromosomes) The gametes produced by the Purple, Smooth parent would be: RS RS RS RS First R and first S First R and second S Second R and first S = Second R and second S = The gametes produced by the yellow, wrinkled parent would be: First r and first s rs First r and second s Second r and first s Second r and second s rs rs rs 2. In the space provided below, make a Punnett Square using these parents. Determine the possible types of offspring (F₁ generation), and answer the following questions: What are the genotypes of the F₁ generation?__ What are the phenotypes of the F₁ generation?
4. A true-breeding strain of wheat that has brown kernels is crossed with a true-breeding strain that has white kernels. The F₁ generation has all brown kernels.

1- In pea plants, purple flower is completely dominant over white flower and round seed is completely dominant over wrinkled seed. A student crosses a heterozygous purple flower/round seed plant with a white flower/wrinkled seed pea plant. Construct a Punnett square to determine the phenotypic ratio of the offsprings. Show all work by drawing a Punnett square and stating what the phenotypes are.
