A plant of genotype C/C;d/d is crossed to c/c;D/D, and the F1 is testcrossed. If the genes in question are unlinked, the percentage of double homozygous recessive individuals in the offspring of the testcross will be:

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
