Question: Two experimental varieties of strawberry are produced by crossing a hexaploid line that contains 48 chromosomes and a tetraploid line that contains thirty-two chromosomes. Experimental variety 1 contains 40 chromosomes, and experimental variety 2 contains 56 chromosomes
Do you expect both experimental lines to be fertile?No, only tetraploid line wil be fertileNo, only hexaploid line will be fertileYes, both experimental line will be fertileNeither line is expected to be fertileHow many chromosomes from the hexaploid line are contributed to experimental variety 1?
How many chromosomes from the hexaploid line are contributed to experimental variety 2?
How many chromosomes from the tetraploid lines are contributed to experimental variety 1? How many chromosomes from the tetraploid lines are contributed to experimental variety 2?
The structure of biological membranes is estimated primarily by the lipid bilayer but the specific functions of these membranes are carried out through proteins associated with the membrane.

In winter, plants exchange the saturated lipids in their membranes for unsaturated lipids. Unsaturated lipids are "bent" and keep the membranes more fluid since they cannot be stacked closely together. Of what benefit would this be for herbaceous pla..
