Agardener crosses tall true–breeding pea plants with short true–breeding ones. tall plants are dominant to short ones. he collects the seeds to grow f1 plants and then allows them to self–pollinate to form an f2 generation. which of the following describes the traits of the offspring correctly?

1.three–fourths of the f1 and one–half of the f2 plants will be tall.
2.all of the f1 and three–fourths of the f2 plants will be tall.
3.three–fourths of the f1 and all of the f2 plants will be tall.

What best describes the dropping height of a ball that bounces back up to a height of 45 cm

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
