In a certain breed of cats, having black hair is the result of 2 dominant alleles for hair color (HH). The heterozygous genotype (Hh) produces a cat that has black and white spots. Having 2 recessive (hh) genes results in a white-haired cat. The Punnett square below shows the results of a cross between which 2 cats? a. a black cat and a spotted cat b. 2 spotted cats c. 2 black cats d. a spotted cat and a white cat
a. a black cat and a spotted cat

Arial's home is sprayed with a pesticide to control an insect pest. SHe didnt see any of the insects for a long period of time, but eventually she begins to see insects again. THe next time the exterminator sprayed her house, they used the same pesticide, and it had no effect on the insect pest. What is the best way to explain this change in survivorship of the pests' population? a. The original insect population did not pass on their genes to their offspring. b. The insects learned to avoid the pesticide. c. THe insects with pesticide-resistant traits survived and reproduced. d. THe original insect population ws not very diverse.
c. THe insects with pesticide-resistant traits survived and reproduced.
