Cc dd and cc dd individuals were crossed to each other, and the f1 generation was backcrossed to the cc dd parent. 997 cc dd, 999 cc dd, 1 cc dd, and 3 cc dd offspring resulted. (a). how far apart are the c and d loci? (b). what progeny and in what frequencies would you expect to result from testcrossing the f1 generation from a cc dd x cc dd cross to cc dd? (c). in a typical meiosis, how many crossovers occur between genes c and d? (d). assume that the c and d loci are on the same chromosome, but the offspring from the testcross described above were 498 cc dd, 502 cc dd, 504 cc dd, and 496 cc dd. how would your answer to part (c) change?

answer; the above answer to the above statement is (true)

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

i believe the answer would be b. hope it : )

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
