In drosophila ,vestigial (vg) wings and reduced (rd) bristles are both recessive mutations in drosophila. vg and rd are both found on chromosome 2, which is depicted in the map below. a female from a homozygous strain of vestigial flies was crossed with a male from a homozygous strain of reduced bristle flies. the f1 hybrids were phenotypically wild-type (long wings and normal bristles). if a female f1 fly is mated with a vestigial male having reduced bristles, what proportion of the progeny would have long wings and normal bristles?

Secondary succession would most likely be taking place in a(n)

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?
