Awoman who is colorblind (xcxc) can expect - select one: a. 100% of her female offspring to be colorblind b. 100% of her male offspring to be colorblind c. 50% of her female offspring to be colorblind d. 50% of her male offspring to be colorblind

Assuming she reproduces with someone who doesn't have the color blind gene:

XcXc * XCY

There are 4 combinations

XcXC

XcXC

XcY

XcY

As both of the males have the Xc gene, she can expect 100% of her male offspring to be colorblind.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
