In dogs, black (B) is dominant to chestnut (b), and solid color (S) is dominant to spotted (5). What are the genotypes of the parents in a mating that produced 3/8 black solid, 3/8 black spotted, 1/8 chestnut solid, and 1/8 chestnut spotted puppies? (Hint: First determine what genotypes the offspring must have before you deal with the fractions.)

haploid cells;

"d.) carbon dioxide and hydrogen sulfide"

that is wrong, its not thymus.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
