Use the following information to answer the next question. In a breeding experiment, a pure plant with round seeds and green pods (RRGG) was crossed with another pure plant with wrinkled seeds and yellow pods (rrgg). The phenotypes of the F2 generation were: 1780 plants with round and green pods, 620 plants with round seeds and yellow pods, 590 plants with wrinkled seeds and green pods and 195 plants with wrinkled seeds and yellow pods. Which law is proved by the result of this experiment? Law of Segregation Law of Mutation Law of Independent Assortment Law of Dominance

Give only typing answer with explanation and conclusion A true-breeding pea plant with round and green seeds was crossed with a true-breeding plant with wrinkled and yellow seeds. Round and yellow seeds are the dominant traits. The F1 plants were allowed to self-fertilize. What are the following probabilities for the F2 generation? a. An F2 plant with wrinkled, yellow seeds. b. Two out of three F2 plants with round, yellow seeds and one with wrinkled, green seeds. c. Four F2 plants in the following order: one has round, yellow seeds; one has round, green seeds; and two have wrinkled, green seeds. d. An F2 plant will not have round, yellow seeds.
A tall pea plant (homozygous dominant) is crossed to a pea plant that is heterozygous for the gene for height. Create a Punnett Square and use it to answer the following questions: What is the genotypic ratio of the offspring? What is the phenotypic ratio of the offspring? Answers are written as genotype; phenotype a) 50% TT : 50% Tt; 100% tall plants b) 1 TT : 2 Tt : 1tt; 75% tall plants : 25% dwarf plants c) 1 TT : 2 Tt : 1tt; 25% tall plants : 50% medium height plants : 25% dwarf plants
After crossing a tall plant with purple flowers (TtPp) and a dwarf plant with white flowers (ttpp), you obtain the following offspring counts. Assuming independent assortment, what is the expected number of offspring that are short plants with purple flowers? Please round your answer to the nearest integer. phenotype count tall, purple 245 short, purple 252 tall, white 251 short, white 252

Consider a two-factor cross between a pure breeding plants: one with purple flowers and yellow seed pods and another with white flowers and green seed pods. 100% of F1 offspring have purple flowers and green seed pods. If these F1 plants are self-fertilized, what proportion of F2 offspring are expected to have purple flowers and green seed pods? You may assume independent assortment of the flower color and seed pod color alleles. Please give your answer as a decimal rounded to two decimal places (e.g. 0.69).
In sweet pea plants, the trait for purple flowers (P) is dominant to the trait for red flowers (p).Similarly, the trait for long pollen (L) is dominant to the trait for round pollen (l).Two heterozygotes are crossed, yielding the following frequencies for the F1 generation:293 purple long plants;19 purple, round plants ;28 red, long plants ;87 red, round plantsUse the chi-square test to determine if these results are due to independent assortment. detailed explanation ?

Use the following information to answer the next four questions. Tomato Plants In tomato plants, round fruit (R) is dominant to oval fruit (r). Pure breeding plants with red and round fruit (FFRR) were crossed to pure breeding plants with yellow and oval fruit (ffrr). The red and round F1 progeny were then testcrossed to plants that were homozygous recessive for both genes (ffrr) with the following results: Phenotypes Number of Offspring Red and round 2 255 Red and oval 290 Yellow and round 310 Yellow and oval 2 145 Part A: Record the phenotypes and the phenotype ratio in lowest terms. Part B: Convert the expected phenotypic ratio from Part A into the expected probability for each of the four phenotypes and record them in the table below. Calculate the probability for each of the four phenotypes observed in the cross from the data presented at the beginning of the question by dividing the number of progeny in each class by the total number of progeny and record these…
