In garden peas, the allele for tall plants (t) is dominant over the allele for dwarf plants (t). a true-breeding tall plant is bred with a true-breeding dwarf plant to produce heterozygous tall plants. the f1 heterozygotes then self-fertilize to yield f2 offspring. complete the punnett square for this monohybrid cross using the f1 gametes with the appropriate genotype and placing the correct f2 genotype/phenotype combination in the punnett square.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
