- 1. In pea plants, yellow peas are dominant to green peas and purple flowers are dominant to white flowers. For each of the following parental crosses, give the predicted phenotypic and genotypic ratios of the F1 generation. Make punnet squares if necessary. 1. (heterozygous purple-flowered) x (heterozygous purple-flowered) 2. (true breeding white-flowered, yellow pea) x (true breeding purple-flowered, green pea) 3. (heterozygous purple-flowered, yellow pea) x (heterozygous purple-flowered, yellow pea) 2. You have a purple-flowered pea plant. You do not know its genotype. Diagram the test-cross you would conduct to determine the plant’s genotype and what results you would expect if the plant was heterozygous and if the plant was homozygous 3. You are studying five traits in Pentids, an amazonian flying beetle. You have identified each trait as belonging to separate alleles located on separate chromosomes and have categorized those alleles as A,B,C,D, and E, respectively. After years of…1. Imagine you have crossed a pure breeding purple flower and pinched pod shape pea plant with a pure breeding white flower and round pod shape pea plant. What would the phenotype be with respect to the flower color and the pod shape in the F1 generation? ” 2. If one of the F1 was allowed to cross-fertilize, what would be the possible phenotypes in the F2 and how many of each phenotype would you predict out of a total of 200 F2 progeny?”5. In garden peas, green pod (P) is dominant to yellow pod (p) and tall stemmed (T) plants are dominant to short stemmed plants (t). Please give the genotypic and phenotypic ratios from the following crosses. a) Homozygous green pod homozygous tall stemmed plant crossed with a yellow pod (homozygous) short stemmed (homozygous) plant. b) Homozygous green pod homozygous tall stemmed plant crossed with a heterozygous green pod heterozygous tall stemmed plant. c) Heterozygous green pod heterozygous tall stemmed plant crossed with a heterozygous green pod heterozygous tall stemmed plant. d) Heterozygous green pod homozygous tall stemmed plant crossed with a yellow pod (homozygous) homozygous tall stemmed plant.

A plant with purple flowers and long pollen (AaBb) is crossed with one that is recessive for both traits (aabb). Calculate the…
- 4. In pea plants, tall (T) plants are dominant to short (t), and green pods (G) are dominant to yellow (g). Perform a Punnett square analysis for the following crosses, with the parental gametes and all possible offspring genotypes that could be produced. **Include the phenotypic ratios for the offspring. (a) TtGG × TTgg2 (a) The trait of hen- versus cock-feathering is a sex-limited trait controlled by a single gene. HH and Hh males always exhibit the hen-featuring trait. Only hh males show the cock-feathering trait. Starting with two heterozygous fowls that are hen- feathered, describe how you would obtain a true-breeding line that always produces cock-feathered males. [Ciri berhulu avam hatin1. Sunflowers with small flowers measuring 10 cm in diameter are crossed with plants that have large flowers with a diameter of 16cm. All offspring in the F1 generation have medium size flowers with 13 cm in diameter. When crossing two F1 generation flowers, the F2 generation shows 4 flowers are 10 cm in diameter and 4 are 16 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. a) Assuming that the alleles that contribute to flower diameter act additively, how many genes control flower size? b) How much does each additive allele contribute to flower diameter? c) What size flower makes up the largest phenotypic class?
