In the Primula plant, the blue flower color is due to malvidin, a pigment encoded by the completely dominant gene (M). Presence of only the recessive gene (m) leads to white flowers. The P locus controls pigment synthesis in the M locus such that dominant gene (P) stops pigment production, and recessive gene (p) allows pigment production. Two plants both having the MmPp genotype were crossed. What would be the probability of getting plants that are pure-breeding for blue flower color?
Anthocyanin is a pigment that gives flowers and leaves purple colors. The M gene codes for a transcription factor (Myb) that promotes expression of an enzyme that produces anthocyanin. The W gene codes for a different enzyme (Chs) that allows anthocyanin to be deposited in plant leaves and flowers. The dominant phenotype is the production of functional Myb and Chs.
1) Plants that have the mm genotype do not show any purple color. What is the best explanation for why this is?
a) Anthocyanin cannot be deposited into the flowers and leaves
b) Anthocyanin is not produced in the plant cells
c) The M gene is codominant to the W gene
d) The M gene is epistatic to the W gene
2)Assume a plant has the genotype MMww. Would this plant have any purple flowers?
a) Yes
b) No
In zucchinis there are two genes controlling flower colour. One gene determines if
pigment is produced or not (P = pigment, p = no pigment) and another gene controls
the colour of the pigment (O = orange, o=yellow). Which of the following
genotypes will produce Orange flowers?
a) Pp Oo & PP OO
b) pp Oo & pp 00
O c) pp oo & Pp oo & PP oo

- Two different genes control the expression of kernel colour in Mexican black corn: black pigment gene B and dotted pigment gene D. Gene B influences the expression of gene D. The dotted phenotype appears only when gene B is in the homozygous recessive state. A colourless variation occurs when both genes are homozygous recessive. What would be the phenotypic ratio of a test cross with a plant heterozygous for both traits? Your response must include a Punnett square with appropriate nomenclature. Show the ratio as whole numbers in their lowest form and their corresponding phenotypes.arrow_forward1) In the plant Salvia, two genes determine the inheritance of flower colour. For one gene, P is the allele for purple colour and p for pink. However, at least one dominant allele at the other locus is required for the colour to be expressed, Plants with the genotype aa have white flowers. Write down all possible genotypes for a) purple flowered b) pink flowered c) white flowers d) which gene, A/a or P/p is the epistatic gene and which is the hypostatic gene? e) What type of epistasis is this?arrow_forwardIn a species of tree, seed color is determined by four independently assorting genes: A, B, C, and D. The recessive alleles of each of these genes (a, b, C, and d) produce abnormal enzymes that cannot catalyze a reaction in the biosynthetic pathway for seed pigment. This pathway is diagrammed as follows: A White precursor Yellow ----Orange----- Red --- Blue When both red and blue pigments are present, the seeds are purple. Trees with the genotypes Aa Bb Cc Dd and Aa Bb Cc dd were crossed. (a) What color are the seeds in these two parental genotypes? (b) What proportion of the offspring from the cross will have white seeds? (c) Determine the relative proportions of red, white, and blue offspring from the cross.arrow_forward

- In wheat, aleurone cells form a thin layer of the seed coat that is critical to early gene expression in plant development. The color of this layer of cells is controlled by two alleles of a gene [colored aleurone (R) is dominant to colorless (r)]. A second gene is known to control the color of leaf tips [green leaf tip (G) is dominant to yellow (g)]. Two plants, each heterozygous for both characteristics, are test crossed to homozygous recessives, and their progeny are combined to produce the following totals: colored green 102 colored yellow 98 colorless green 103 colorless yellow 97 a) Use chi-square analysis to test these data for an independent assortment of the two characteristics (table provided). Please show work, how your expected values are calculated, and explain what your results indicate about the data. b) You decide to be cautious in your analysis, and decide to analyze the progeny from each of the crosses individually (instead of adding them together as shown above).…arrow_forwardA mutation that breaks which of the following genes would be most likely to produce theanthocyanless phenotype of the green-stem Wisconsin Fast Plants (meaning no purple stems):PAL, CHS, C3H, FLS, or DFR?
