Instruction: Observe the process used in plant and animal reproduction. A. Put a Check (/) if the process helps to produce offspring with genetic variation, then put a cross (x) if it produces offspring with no genetic variation. Process Genetic Variation in Offspring 1. Self pollination of a flower 2. Plant Cutting 3. Germination of seeds 4. Stolons producing new plants

II III 51 6. Section 5: Trihybrid cross and Laws of probability For a trihybrid cross, in which inheritance of alleles for three genes is tracked; drawing a Punnett square that combines all three genes may not be practical. Instead the laws of probability may be used. The product law of probabilities says that when alleles for separate genes segregate independently, we can figure out the probability of a particular combined genotype by multiplying the probability of the alleles for each gene. 13. We cross a homozygous tall pea plant with yellow, round seeds to a homozygous dwarf pea plant with green, wrinkled seeds. All the F1 offspring are all tall plants with yellow, round seeds. a. What are the expected F2 ratios (use fractions) of tall and dwarf plants? b. What are the expected'F2 ratios (use fractions) of yellow and green seeds?

What height should all F1s display if  the shortest and tallest plants were crossed, assuming environmental factors are the same

Instructions: Answer the following problem using the punett square and identify its Genotypic ratio and Phenotypic ratio. 1. A homozygous round-seeded plant (RR) is crossed with a homozygous wrinkle-seeded plant (rr). What is the phenotypic and genotypic ratio of their offspring? Genotypic Ratio Phenotypic Ratio- 2. A heterozygous green-colored pod (Gg) is crossed with a yellow-colored pod (gg). Predict the Genotypic and Phenotypic ratio of their offspring. Genotypic Ration Phenotypic Ration

I. Perform the indicated single-gene and two-gene crosses. Show all work. Show all Punnett squares. List the gene or genes involved, list and define all allele symbols, and indicate the genotypes of the individuals you are crossing above the Punnett square. Answer questions that ask for a ratio as a ratio and questions that ask for a percent as a percent. In snapdragon plants, the alleles for flower color show incomplete dominance. First show a cross of two parents, one with red flowers and the other with white flowers. Then show a cross of two of the F1 plants to get the F2 generation. Indicate the genotype ratio and phenotype ratio for both the F1 and F2 generations.

Topic: Trihybrid Cross, Height in merigonias is determined by three unlinked genes that act additively. Each has two alleles, one compltely dominant allele(A,B or C) that makes plants taller and one recessive allele that makes plants shorter. Do the corss AaBbCc X AaBbCc. The F1 progenty: 27/64 will be as tall as the parents; 37/64 will be shorter than the parents. Pls explain it with more details. thanks

Practice 3, no points. A variety of pea plant known as Blue Pamlico produces a tall plant with blue seeds. A second variety of pea plant called Mulberry Dwarf produces a short plant with white seed. The two varieties are crossed and the seeds are collected. All the seeds are white. When planted, the seeds all produce tall plants. These tall plants are allowed to self-fertilize. For the F2 generation, 94 plants had blue seeds and were tall, 272 plants had white seeds and were tall, 31 plants had blue seeds and were short, and 89 plants had white seeds and were short. a)Which phenotypes are dominant and why? b)What would be the expected distribution of phenotypes in the F2 generation if the alleles of the genes assort independently? c)Perform chi square analysis on the distribution of phenotypes in the F2 generation d) Are these results consistent with the hypothesis of independent assortment? Explain using the results of your chi squared analysis.
