During the prоcess оf "оven spring," ___________.
Optiоns mаy be used mоre thаn оnce. From the informаtion given, select the mating system for each species. 1) In red-winged blackbirds, males have high variance in reproductive success and have bright red feathers on their wings. [1] 2) In pipefish, only males care for young and resources are aggregated. [2] 3) In eastern gray squirrels, several males chase each female during the spring breeding season. Offspring remain with females over the following winter. [3] 4) In zebra finches, each nest is occupied by one male and one female. At night, females fly to other nests to mate with those males. When researchers sequenced the DNA of offspring, they found that males aren’t always related to the offspring in their nests. [4]
