Which of the following would you expect to exhibit the greatest diversity in their offspring?
a) amoebas produced by binary fission
b) sunflowers produced from the seeds of cross-pollinated plants
c) potato plants grown from cuttings of a tuber
d) hydras which have arisen by budding from a single parent
so any ideas?

"B" But I don't believe the answers suggesting it was obvious are anything but those wanting to toot their own horns because no one else will. They are the type of people who would stifle progression by holding down and limiting the expansion of individual knowledge much they same way as those in power in Germany did around 1936 til the end of their reign. They were afraid of what knowledge in the possession of the masses would bring. Enough of that. The reason that "B" is correct is because it is the only choice that allows for the the DNA input of 2 individual components. Hats off to you for wanting to expand you knowledge, and don't ever be afraid to ask, or let someone put you down for asking; remember, the only dumb question is the one you don't ask!!

The sunflowers are the only non-cloned example - the only one which is not a genetic copy of its parent. Furtherly, the cross-pollination brought in other genes from at least a different strain of sunflower. This is the value of sexual reproduction, from a biological pouint of view - the recombination of available genes brings a great diversity into the offspring that increases the chance that even as conditions change there will be one or more of the progeny that have a winning genetic combination to succeed.
Those poor clonal creatures - one wonders how they've managed it as well as they have for so long ! LOL!

I choose the sunflowers because cross pollination promotes genetic variation in the population, allowing for the expression of different phenotypes within the species. With the other choices, the offspring are basically genetic copies of their parents.

(B) The other ones only involve one parent, or one set of genes which doesnt have any diversity. By cross pollination you have 2 different parents, or 2 different sets of genes

sturdy element. unquestionably the whole rule is i in the previous e different than after c, or sounding like a as in neighbor or weigh. Protein is one extra exception. in easy terms 80 % of English is widely used (follows the guidelines). i'm effective happy that is my interior of sight language. I do like it nevertheless. i assume that is contagious as my daughter is now coaching severe college English. We make it a game to objective to capture one yet another's grammar blunders.

I am certainly not a science person but from a nursing point of view any plant or animal without both male and female, I would think would be missing DNA

It's B, the only example given of sexual reproduction. Sexual reproduction always produces greater diversity then asexual means of reproduction.

Option b) is correct.
during crosspollination there is intermixing of characters which is the primary requisite for producing variation.

Answer b is correct. It is the only one which can have different genetics than the parent (absent mutations).

(b) but it's just a guess. It's been 30 yrs since I've taken biology!
