1. A gardener harvested 3,697 seeds from cross breeding a pure line red-flower petunia and pure line white-flower petunia. Then, he planted the harvested seeds in a 25x25 m plot. He was shocked that all of his planted petunias produced red flowers. Why? A. The red flower petunia is a dominant trait. B. The red flower petunia is a recessive trait. C. The white flower petunia is a dominant trait. D. The white flower petunia has a heterozygous genotype in flower color. 2. A veterinary doctor found a long tail female cat along the way going to her clinic. She wanted to know if the long tail female cat is a pure breed/line or not? So as a Biology student with genetic subject, which of the following choices can you correctly suggest to her? Considering the long tail trait as dominant trait. A. She must cross breed it with a short tail female cat B. She must do a back cross breeding with a short tail male cat C. She must run a molecular test for the long tail female cat…
1. Suppose you are studying a trait due to three genes that all additively affect the same trait. The genes are A, B, and C. Capital letters symbolize the "phenotype-adding" allele and lower case letters symbolize the "non-adding" allele. (In other words, the behavior of the genes is like those affecting wheat kernel color in the Nilsson-Ehle experiment presented in class). If AaBbCc is testcrossed to aabbcc, how many different phenotypes will be produced in the progeny?
Fruit weight is controlled by 4 gene pairs. The homozygous dominant weighs 200 g while the homozygous recessive weighs 80 g. Assume that the alleles have equal contribution and have cumulative effects. The F1 and F2 of the two parents below were studied Parent 1 Parent 2 B1B1B2B2B3B3b4b4 x b1b1b2b2b3b3B4B4 a.) Compute for the contribution of the dominant allele. b.) Compute for the fruit weight of parental 1 and parental 2. c.) Provide the genotype and phenotype of the F1. d.) Compute for the frequencies of the different individuals in the F2.
1. Use the following information to answer the question: Parental cross is RrYy x RrYy Seed Shapes are R-round, r-wrinkled Seed colors are Y-yellow, y-green Based on the information given, what is the phenotype ratio of the offspring of this cross? 2. A pea plant heterozygous for height and seed color (TtYy) is crossed with a pea plant heterozygous for height but homozygous recessive for seed color (Ttyy). If 80 offspring are produced, how many are expected to be tall and have yellow seeds? 3. What is the chromosome theory of inheritance? How does this theory explain Mendel's results? 4. A cross between two organisms heterozygous for two different genes (AaBb) results in a 9:3:3:1 phenotype ratio among the offspring. Is the offspring's genotype ratio the same? Explain your answer.…
2. In terms of pea plant height, tall plants (T) are dominant over dwarf plants (t). Purple flowers (P) are dominant over white flowers (p). Create a Punnett square that shows all of the possible offspring that could occur from breeding the following: a.) Plant 1: Heterozygous dominant for plant height, homozygous dominant for flower color b.) Plant 2: Heterozygous dominant for plant height, homozygous recessive for flower color c.) Include the percentage/ratio of occurrence for each phenotype.
5. You are handed a mystery pea plant with tall stems and axial flowers and asked to determine its genotype as quickly as possible. You know that the allele for tall stems (T) i dominant to that of the dwarf stems (t) and that allele for axial flowers (A) is dominant to that for terminal flowers (a). (a) What are all the possible genotypes of your mystery plant? (b) Describe the one cross you would do, out of your gardens, to determine the exact genotype of your mystery plant. (c ) While waiting for the results of your cross, you predict the result of each possible genotype listed in part a. How do you do this? Why is this not called "performing a cross"? (d) Explain how the results of your cross and your predictions will help you learn the genotype of your mystery plant.

Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?
