Textbook Question
Chapter 46, Problem 11TYU
SCIENTIFIC INQUIRY You discover a new egg-laying worm speties. You dlssect four adults and find both oocytes and sperm in each. Cells outside the gonad contain five chromosome pairs. Lacking genetie variants, explain how you would determine whether the worms can self-feriilize.

Students have asked these similar questions
1: Make a diagram of the life cycle of a diagenetic fluke worm (Class Trematoda).
2: Highlight the stage(s) of life cycle that reproduce sexually and which are capable of asexual reproduction.
3: Explain the advantages of having a life cycle with both sexual and asexual phases.
6)From the menu on the left on Virtual Urchin, click on "embryogenesis to hatching". This will display a video of sea urchin development. Photos of key stages taken with a scanning electron microscope (SEM) are shown next to the video. In addition to watching the video by clicking the play button, you can use the slider at the bottom to move through the stages step by step. Doing this will allow you watch how cell division increases the number of cells from the initial zygote. You'll notice that these divisions start off dividing cells evenly, but at a certain point, there are some smaller cells created. These smaller cells will play very important roles in the later development stages of the urchin, so their creation is a key milestone.
Which round of cell division is uneven? (hint: the SEM images will be helpful)
a)First
b)Second
c)Third
d)Fourth
e)Fifth
Explain well which option is correct, why
