Tall is dominant to short among pea plants. Choose appropriate symbols for these two traits and using these symbols write out a cross between true-breeding tall plants and true-breeding short plants. Be sure to include a legend and indicate what percentage of the offspring would be expected to show a given trait. a. If the offspring were allowed to self- fertilize, what phenotypes and genotypes would be expected among the offspring and in what proportion? Using the symbols selected in the original problem, write out this cross and the resulting offspring. Please use Punnett square for this problem.

b. If the offspring were mated to true-breeding short plants, what phenotypes and genotypes would be expected among the offspring and in what proportion? Using the symbols selected in the original problem, write out this cross and the resulting offspring. What is this kind of cross called?

c. If the offspring were mated to true-breeding tall plants what phenotypes and genotypes would be expected among the offspring and in what proportion? Using the symbols selected in the original problem write out this cross and the resulting offspring.

Svetlana and her mother are very similar. both have blonde hair, a love of scrapbooking, blue eyes, and a thin nose. which statement  most likely  describes svetlana’s traits? svetlana inherited her love of scrapbooking from her mother, but her blue eyes come from her environment.svetlana inherited her blue eyes from her mother, but her love of scrapbooking comes from her environment.svetlana inherited her thin nose from her mother, but her blonde hair comes from her environment.svetlana inherited her blonde hair from her mother, but her thin nose comes from her environment.

Rease is an enzyme used by plants to break down urea (a nitrogen-containing compound) into carbon dioxide and ammonia. urease urea > > > carbon dioxide and ammonia ammonia is broken down by plants into a nitrogen source plants need to grow. thus, plants could not use urea as a nitrogen source unless it was first converted to ammonia. in soybean plants there are two different kinds of urease, one produced in the seeds and the other produced in the leaves of the plant. three types of soybean plants were used in a set of experiments: normal soybeans and two mutant strains, one lacking the urease in the seeds only (strain 1) and one lacking urease in the leaves only (strain 2). experiment 1 separate areas in a field were planted with normal, strain 1, and strain 2 soybeans. all types of soybeans appeared to grow, flower, and produce seeds equally well. there were no externally detectable differences among the strains. experiment 2 small pieces of plant leaves of equal weight were obtained from each type of soybean plant and separately placed on media in culture dishes. tissue growing in this way will become an unorganized clump of cells referred to as callus. to provide a controlled nitrogen source, half the tissue samples of each type were placed on media containing urea, and the other half of the samples were placed on media containing ammonia. after 30 days, the weight gain for each of the callus samples was determined. results are shown in the table below.
