Algae absorb carbon dioxide, a major greenhouse gas, as a part of photosynthesis. Other plants also do this, but algae grows the quickest. Hope this helps!!!
The genotype would be X'Y for the father (he would be colorblind) The genotype would be X'X for the mother (she would be a carrier) The offspring would be X'X' _ X'X_ X'Y_ XY The ratio would be 1:1 normal to colorblind Hope this was helpful(;
