Question

before modern genetics was understood, the concept of pangenesis was accepted. what best describes pangenesis? acquired characteristics blending of genes dna heritability natural selection

Explanation:

Pangenesis, proposed by Darwin, suggests that particles (gemmules) from all parts of the body collect in gametes. These gemmules represent acquired characteristics from different body parts. Blending of genes is a different concept (mixing of parental traits). DNA heritability is related to modern genetics (not pangenesis). Natural selection is about survival and reproduction of fittest (not pangenesis).

Answer:

acquired characteristics
