The f1 generation differed from the f2 in mendel's experiments in that __________. all of the f1 showed the dominant phenotype,
and all of the f2 showed the recessive phenotype one-half of the f1 showed the dominant phenotype, and three-fourths of the f2 did all of the f1 showed the dominant phenotype, but only three-fourths of the f2 did none of the f1 showed the dominant phenotype, but one-half of the f2 did all of the f1 showed the dominant phenotype, whereas only half of the f2 did
The F1 generation differed from the F2 in the Mendel's experiments in that all the F1 generation showed the dominant phenotype, however only three- fourths or three quarters of the F2 generation did. This is because all the F1 generation were heterozygous and thus the dominant phenotype was expressed, while in the F2 generation there was a mixture of homozygous dominant, homozygous recessive and heterozygous. Therefore, the heterozygotes and the homozygotes dominant showed a dominant phenotype.
Facilitated diffusion takes place due to a difference in concentration on both sides of the membrane, in the direction of the lowest concentration, and does not require energy.
Living and Nonliving Things in the Ecosystem. Ecosystems -- biological communities -- include living organisms like animals, plants, insects and bacteria, as well as nonliving components like rocks, soil, water and sunlight.
