Determine whether the ratio of corn kernels support the hypothesis that the plant is heterozygous.arrow_forwardMore Crosses with Pea Plants: The Principle of Independent Assortment In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all three loci is self-crossed, and 2,048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled peas?arrow_forward
- Analysis of Autosomal Recessive and Dominant Traits In the following pedigree, assume that the father of the proband is homozygous for a rare trait. What pattern of inheritance is consistent with this pedigree? In particular, explain the phenotype of the proband.arrow_forwardMore Crosses with Pea Plants: The Principle of Independent Assortment Given the following matings, what are the predicted phenotypic ratios of the offspring? a.

- More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?arrow_forwardVariations on a Theme by Mendel Pea plants usually have white or red flowers. A strange pea-plant variant is found that has pink flowers. A selfcross of this plant yields the following phenotypes: 30 red flowers 62 pink flowers 33 white flowers What are the genotypes of the parents? What is the genotype of the progeny with red flowers?arrow_forwardCrossing Pea Plants: Mendels Study of Single Traits Of the following, which are phenotypes and which are genotypes? a. Aa b. tall plants c. BB d. abnormal cell shape e. AaBbarrow_forward
- Crossing Pea Plants: Mendels Study of Single Traits An unspecified characteristic controlled by a single gene is examined in pea plants. Only two phenotypic states exist for this trait. One phenotypic state is completely dominant to the other. A heterozygous plant is self-crossed. What proportion of the progeny of plants exhibiting the dominant phenotype is homozygous?arrow_forwardAt the molecular level (with regard to loss-of-function alleles), explain why the ttvv homozygote has an ovate seed capsule.arrow_forwardmust answer all other don't answer i need all part solvve Two pea plants are crossed, which are purebred. A father is round, terminal, violet and wrinkled, while the other expresses the phenotypes alternate rough, axial, white, and swollen. The four pairs of characters alternatives are regulated by four genes, each located in different chromosomes. In Fx only the characters round, axial, purple and puffy. In F2 all possible combinations of these characters according to Mendelian inheritance. (a) to what conclusions we can reach about the inheritance of these characters, based on the F1 results? (b) In the results of F2, what phenotype will appear more often? Write a mathematical expression that predict the probability of occurrence of said phenotype. (c) In the results of F2, which phenotype will appear less frequently? write an expression mathematics that predicts this probability. (d) In the F2 generation, with what probability will each of the two phenotypes of P1 appear? (e) If a…arrow_forward
