The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)

Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
Simple sugars provide no other nutritional values besides energy; cause jolt in energy and then a run-down soon after. Complex sugars provide an extended sustained source of energy that are believed to be better for health and energy.
Recombinant DNA innovation gave an approach to researchers to create human insulin in the lab. The quality for human insulin is disengaged from human cells and embedded into plasmids. These plasmids are then brought into bacterial cells, which produce the insulin protein in view of the human code.
Recombinant DNA are currently used for all of the above (d).
