Five closely related species of frogs live in ranges that overlap. some breed in woodland ponds, some in lowland swamps, and some in streams. how do these five species of frogs remain separate and do not attempt to mate? a line graph plots mating activity of 5 frog species over time, which ranges from march to july. the graph for each species is a bell-shaped curve. each curve overlaps with 1 or 2 neighboring curves. from left to right, the curves are labeled wood frog, leopard frog, pickerel frog, green frog, and bullfrog. study the graph and the text to identify two modes of isolation. a. temporal isolation: the species remain separate because the period of most active mating differs. b. behavioral isolation: each species has a courtship pattern that allows males and females to recognize each other. c. geographical isolation: the species remain separate because they have different breeding sites. d. reproductive isolation: the sperm of one species cannot fertilize the eggs from another species.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).

Number and variety of living organisms includes genetic, species, and ecological types

What was the purpose of mendel's experiments with dihybrid crosses? a. to determine if dna was a transforming factor b. to determine if traits could be recessive c. to determine if traits affected each other d. to determine if traits had more than one allele
