Sexual reproduction appears to be absent in bdelloid rotifers. which of these, if found in this group, would bring into question the idea that they reproduce only asexually?

 Sexual reproduction in humans allows a haploid sperm cell to fertilize a haploid egg cell. It also appears to be absent in bdelloid rotifers, cells in which meiosis occurs would bring into question the idea that they reproduce only asexually. Meiosis does not produce cells genetically identical to the parent cell.

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)
