- Question:- What would be the effect on flowering time of over-expressing VIN3 (i.e., 35S:VIN3) in a winter annual Arabidopsis plant grown adjacent to a summer annual wild type plant in long days under warm conditions? Assume that the plants germinate at the same time. In answering the question, describe the molecular mechanism that allows you to make this conclusion.Plants reproduce through various methods. Explain which method helps to create genetic variability in crop plants? Moreover elaborate mechanisms promoting self or cross pollination.Predict the phenotype of a flower in whichAPETALA-2 (activity A) and AGAMOUS (activity C) are expressednormally, but APETALA-3 and PISTILLATA (activity B) areexpressed in all four whorls.
- What is a feasible explanation why there is lesser percentage of germination and growth rate in monggo seeds when sprinkled with water added with 3/4 teaspoon as compared to monggo seed set-ups sprinkled with water?A 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? Explain your reasoning.Because snapdragons (Antirrhinum) possess the pigment anthocyanin, they have reddish purple petals.Two pure anthocyaninless lines of Antirrhinum weredeveloped, one in California and one in Holland. Theylooked identical in having no red pigment at all, manifested as white (albino) flowers. However, when petalsfrom the two lines were ground up together in buffer inthe same test tube, the solution, which appeared colorless at first, gradually turned red.a. What control experiments should an investigatorconduct before proceeding with further analysis?b. What could account for the production of the redcolor in the test tube?c. According to your explanation for part b, what wouldbe the genotypes of the two lines?d. If the two white lines were crossed, what would youpredict the phenotypes of the F1 and F2 to be?
- This experiment is done in a thermal flask, will you be able to perform the same results (flask A with germinated seeds temperature increases and flask B with boiled seeds temperature remain unchanged), assuming you will be using a regular glass flask? Why?"Conservative and compensatory evolution in oxidative phosphorylation complexes of angiosperms with highly divergent rates of mitochondrial genome evolution" Article Abstract Interactions between nuclear and mitochondrial gene products are critical for eukaryotic cell function. Nuclear genes encoding mitochondrial-targeted proteins (N-mt genes) experience elevated rates of evolution, which has often been interpreted as evidence of nuclear compensation in response to elevated mitochondrial mutation rates. However, N-mt genes may be under relaxed functional constraints, which could also explain observed increases in their evolutionary rate. To disentangle these hypotheses, we examined patterns of sequence and structural evolution in nuclear- and mitochondrial-encoded oxidative phosphorylation proteins from species in the angiosperm genus Silene with vastly different mitochondrial mutation rates. We found correlated increases in N-mt gene evolution in species with fast-evolving…"Conservative and compensatory evolution in oxidative phosphorylation complexes of angiosperms with highly divergent rates of mitochondrial genome evolution" Article Abstract Interactions between nuclear and mitochondrial gene products are critical for eukaryotic cell function.

- In roses, the synthesis of red pigment is by two steps ina pathway, as follows:colorless intermediate gene Pmagenta intermediate red pigment gene Qa. What would the phenotype be of a plant homozygousfor a null mutation of gene P?b. What would the phenotype be of a plant homozygousfor a null mutation of gene Q?c. What would the phenotype be of a plant homozygousfor null mutations of genes P and Q?d. Write the genotypes of the three strains in parts a, b,and c.e. What F2 ratio is expected from crossing plants fromparts a and b? (Assume independent assortment.)When tomatoes are fully ripe, they develop bright red skins. William recently built a garden and decided to investigate tomato reproduction. He found that green tomatoes (not fully ripe) have an 18% chance of germinating while red tomatoes (fully ripe) have a 78% chance of germinating. Based on the data provided from the investigation, explain what characteristic(s) contributes to the probability of the tomatoes reproductive success and what factors (genetic or environmental) might impact the growth and development of the tomatoes. Answer should be based on : Claim: includes the idea that characteristic animal behaviors or specialized plant structures affect the probability of successful reproduction. Evidence: supports claim including: -behaviors and/or structures that increase the probability of reproduction -cause and effect relationship between the behavior/structure and the successful reproduction of organisms that have them -plant reproduction and the animal behaviors…Normally, wild violets have yellow petals with darkbrown markings and erect stems. Imagine you discover a plant with white petals, no markings, andprostrate stems. What experiment could you performto determine whether the non-wild-type phenotypesare due to several different mutant genes or to thepleiotropic effects of alleles at a single locus? Explainhow your experiment would settle the question.
