Question

Some lizards can undergo both sexual and asexual reproduction. Being able to reproduce asexually benefits the organism during times when mates are hard to find. Under what circumstances would asexual reproduction be most beneficial?

The species finds its life span is increasing rapidly.

The species finds itself falling prey to a new and well-adapted predator.

The species needs to adapt to a dwindling source of food.

The species needs to develop resistance to a new type of disease

Answer 1

I think its D

Answer 3

IF in the case of answer b the individual is a homozygote (so both allels capturing the information for (example) a black fur which is pleasing to have) this could be a good answer, but since we don't know it, you would be probably right with the answer of your choice :)

Answer 4

Don't try to imagine a lizard with a black fur... it's just an example that would make sense if lizards would have taken care of furs in some previous evolutionary steps :D But I always think it's fine to describe homozygot :)

Answer 5

Sexual reproduction has the advantage that new combinations of genes are formed, so perhaps better camouflage might result, or indeed resistance to disease. I think this means that you can rule out three answers above which deal with adaptation to new threats like dwindling food supplies, predators or disease.

Answer 6

I'd like to add the significance of new combinations of genes is different phenotypes: this means that they have different characteristics.
