Two pairs of traits are segregating in a cross. Two parents produce 156 progeny that fall into 4 phenotypes. The numbers of offspring in the 4 phenotypes are 89, 31, 28, and 8. What are the genotypes of the two parents?
Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds
Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.
Which recombination frequency corresponds to perfect linkage and violates the law of independent assortment? 0 0.25 0.50 0.75
In peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?
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.…
3. A wild flower has a dominant allele of red-flower color which is incompletely dominant over the allele of white-flower color. Draw the Punnett square for the cross. Identify the flower color phenotypes and theoritical percentage.
4) A testcross is used to determine which of the following? a) The phenotype of an individual with a dominant genotype b) The phenotype of an individual with a recessive genotype c)The genotype of an individual with a dominant phenotype d) The genotype of an individual with a recessive phenotype
