Electrical synapses, I believe.
Conduction and convection are means of transferring heat, the important difference is the medium through which the heat travels. Conduction occurs when heat is transferred through solid objects, like a bar.
The environment can influence the evolutionary changes so that the organism will be best suited to survive in that area. Genes that are useless in that specific environment will eventually be replaced with more useful traits as the species evolves.
Hope that helps
B+ Bb Ww male × B+ Bb Ww female Because beardedness and coat color independently assort, we can treat them independently. The difference between this cross and a dihybrid cross is that the bearded allele B b is dominant in males and recessive in females. So we deal with male and female progeny separately. For each sex, then, we should get a typical dihybrid ratio. In males, the dominant phenotype is bearded, so we should get ¾ bearded, ¼ beardless. In females the dominant phenotype is beardless, so we should get ¾ beardless and ¼ bearded. Each sex will have ¾ black and ¼ white coats.
