In a hypothetical environment, fishes called pike-cichlids are visual predators of large, adult algae-eating fish (in other words, they locate their prey by sight). The population of algae-eaters experiences predatory pressure from pike-cichlids. Which of the following is least likely to result in the algae-eater population in future generations?

#SCPH28 | Zoology
  1. selection for drab coloration of the algae-eaters

  2. selection for nocturnal algae-eaters (active only at night)

  3. selection for larger female algae-eaters, bearing broods composed of more, and larger, young

  4. selection for algae-eaters that become sexually mature at smaller overall body sizes

Individual and overlapping expression of homeotic genes in adjacent whorl of a flower determine the pattern of floral organ development. In an Arabidopsis mutant, floral organs are distributed as follows
WHORL 1 Sepal
WHORL 2 Petal
WHORL 3 Petal
WHORL 4 Sepal
