Explain why sexually reproducing organisms are often better suited to changes in their environment than asexually reproducing organisms.
All sexually-reproducing animals must have certain basic
anatomical structures in order to reproduce sexually. Choose
an animal, identify its sex (e.g. "female nematode") and
answer the questions below:
Briefly describe the organs your chosen animal has that
fit the relevant categories
• Give a brief description (three to four words) of the
function of each listed organ.
Egg laying in fruit flies can be triggered (induced) when males transfer their sperm to females. Which of the following is a selective advantage of induced egg laying for the male flies?
Less time and energy is expended by the male.
The males do not have to produce as much sperm.
More eggs can be fertilized.
A male fly's sperm is more likely to be used for fertilization.
