Mountains of California. Scientists studying the beetles found that exposure
to high temperatures during the summer, when the eggs are laid and the
larvae are developing, causes physiological stress. The impact is on
metabolic enzymes and heat shock protein expression. One allele, pgi-4,
increased in frequency in the beetle population that was exposed to hotter,
drier summers in the Sierra Nevada Mountains.
If the temperature in the Sierra Nevada Mountains continues to increase,
what will happen to the frequency of the pgi-4 allele?
A. Increase
B. Decrease
C. Stay the same

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
